Pneumocephalus Following Combined Spinal-Epidural Anesthesia: A Case Report Analysis

Background: Combined spinal-epidural anesthesia (CSEA) is widely used in clinical anesthesia due to its rapid onset, reliable anesthetic effect, and strong controllability. Although advancements in technique have reduced the frequency and severity of common complications, reports of rare and serious complications such as pneumocephalus, remain scarce. Case Report: This article presents a case of pneumocephalus following CSEA in a middle-aged female patient undergoing surgery for an intrauterine space-occupying lesion. The patient experienced severe headache postoperatively, and imaging confirmed the presence of intracranial air. After receiving active symptomatic treatment, the patient recovered and was discharged. Conclusion: This case underscores the importance of adhering to standard anesthesia protocols and increasing awareness of rare CSEA complications, particularly the risk of pneumocephalus. Early recognition and timely management are crucial. There is a need to further enhance training and research in anesthetic procedures to improve clinical anesthesia quality and ensure patient safety.

Effectiveness and safety of rocuronium or nitroglycerin plus ropivacaine on pain during intravenous regional anesthesia:A double-blind randomized controlled trial

Objective:To compare the effects of adding rocuronium and nitroglycerin to ropivacaine in intravenous regional anesthesia(IVRA)on pain and hemodynamic parameters.Methods:This randomized controlled trial was done in 2023.Participants were 177 candidates for forearm operation surgery under IVRA selected from Valiasr Hospital,Arak,Iran.They were allocated by block randomization to three different groups,namely nitroglycerin group,rocuronium group and control group.Hemodynamic parameters were recorded before tourniquet application up to postoperative recovery time.Sensory block and motor block onset and duration and pain were also evaluated.The data analysis was carried out by IMB SPSS software 20.0.Results:177 Eligible patients were included in study,with 59 in each group.Time to sensory and motor block onset in the nitroglycerin group was significantly less than the other groups and the time of motor block in the rocuronium group was statistically higher than the control and the nitroglycerin groups(P<0.001).Seven participants in the nitroglycerin group experienced headache and three from the rocuronium group experienced dizziness.The side effects occurrence in the nitroglycerin group was more prevalent than in the control and rocuronium groups(P=0.009).Conclusions:Nitroglycerin significantly reduces the time to sensory and motor block onset,while rocuronium is more effective in prolonging the time of motor block.Although there is no difference between nitroglycerin and rocuronium respecting the pain score and opioid need administration,nitroglycerin is associated with a higher prevalence of medication side effects.Therefore,both nitroglycerin and rocuronium can be used as adjuvant for IVRA.The final choice relies on patients’conditions and anesthesiologists’judgment.

Impact of dexmedetomidine-assisted anesthesia in elderly patients undergoing radical resection of colon cancer

BACKGROUND Radical resection of colon cancer under general anesthesia is one of the main treatment methods for this malignancy.However,due to the physiological charac-teristics of elderly patients,the safety of perioperative anesthesia needs special attention.As anα2-adrenergic receptor agonist,dexmedetomidine(Dex)has attracted much attention from anesthesiologists due to its stabilizing effect on heart rate and blood pressure,inhibitory effect on inflammation,and sedative and analgesic effects.Its application in general anesthesia may have a positive impact on the quality of anesthesia and postoperative recovery in elderly patients undergoing radical resection of colon cancer.METHODS A total of 165 colon cancer patients who underwent radical surgery for colon cancer under general anesthesia at Qingdao University Affiliated Haici Hospital,Qingdao,China were recruited and divided into two groups:A and B.In group A,Dex was administered 30 min before surgery,while group B received an equivalent amount of normal saline.The hemodynamic changes,pulmonary compliance,airway pressure,inflammatory factors,confusion assessment method scores,Ramsay Sedation-Agitation Scale scores,and cellular immune function indicators were compared between the two groups.RESULTS Group A showed less intraoperative hemodynamic fluctuations,better pulmonary compliance,and lower airway resistance compared with group B.Twelve hours after the surgery,the serum levels of TLR-2,TLR-4,IL-6,and TNF-αin group A were significantly lower than those of group B(P<0.05).After extubation,the Ramsay Sedation-Agitation Scale score of group A patients was significantly higher than that of group B patients,indicating a higher level of sedation.The incidence of delirium was significantly lower in group A than in group B(P<0.05).CONCLUSION The use of Dex as an adjunct to general anesthesia for radical surgery in elderly patients with colon cancer results in better effectiveness of anesthesia.

Comparison of Propofol and Fentanyl for Preventing Emergence Agitation Following Sevoflurane Anesthesia in Pediatric Patients: A Single-Center Study in Bangladesh

Background: Emergence agitation (EA) is a common phenomenon observed in pediatric patients following general anesthesia. This study aimed to assess the efficacy of propofol and fentanyl in preventing EA and to compare their associated complications or side effects. Methods: This prospective randomized observational comparative study was conducted at Dhaka Medical College Hospital from July 2013 to June 2014. The study aimed to evaluate the effects of propofol and fentanyl on EA in children aged 18 to 72 months undergoing circumcision, herniotomy, and polypectomy operations. Ninety children were included in the study, with 45 in each group. Patients with psychological or neurological disorders were excluded. Various parameters including age, sex, weight, American Society of Anesthesiologists (ASA) class, duration of anesthesia, Saturation of Peripheral Oxygen (SPO2), heart rate (HR), respiratory rate (RR), Pediatric Anesthesia Emergence Delirium (PAED) score, duration of post-anesthesia care unit (PACU) stay, incidence of laryngospasm, nausea, vomiting, and rescue drug requirement were compared between the two groups. Results: Age, sex, weight, ASA class, and duration of anesthesia were comparable between the two groups. Perioperative SpO2 and HR were similar in both groups. However, the PAED score was significantly higher in the fentanyl group during all follow-ups except at 30 minutes postoperatively. The mean duration of PACU stay was significantly longer in the fentanyl group. Although the incidence of laryngospasm was higher in the fentanyl group, it was not statistically significant. Conversely, nausea or vomiting was significantly higher in the fentanyl group. The requirement for rescue drugs was significantly higher in the fentanyl group compared to the propofol group. Conclusion: Both propofol and fentanyl were effective in preventing emergence agitation in pediatric patients undergoing various surgical procedures under sevoflurane anesthesia. However, propofol demonstrated a better safety profile with fewer incidences of nausea, vomiting, and rescue drug requirements compared to fentanyl.

Factors influencing agitation during anesthesia recovery after laparoscopic hernia repair under total inhalation combined with caudal block anesthesia

BACKGROUND Laparoscopic hernia repair is a minimally invasive surgery,but patients may experience emergence agitation(EA)during the post-anesthesia recovery period,which can increase pain and lead to complications such as wound reopening and bleeding.There is limited research on the risk factors for this agitation,and few effective tools exist to predict it.Therefore,by integrating clinical data,we have developed nomograms and random forest predictive models to help clinicians predict and potentially prevent EA.AIM To establish a risk nomogram prediction model for EA in patients undergoing laparoscopic hernia surgery under total inhalation combined with sacral block anesthesia.METHODS Based on the clinical information of 300 patients who underwent laparoscopic hernia surgery in the Nanning Tenth People’s Hospital,Guangxi,from January 2020 to June 2023,the patients were divided into two groups according to their sedation-agitation scale score,i.e.,the EA group(≥5 points)and the non-EA group(≤4 points),during anesthesia recovery.Least absolute shrinkage and selection operator regression was used to select the key features that predict EA,and incorporating them into logistic regression analysis to obtain potential pre-dictive factors and establish EA nomogram and random forest risk prediction models through R software.RESULTS Out of the 300 patients,72 had agitation during anesthesia recovery,with an incidence of 24.0%.American Society of Anesthesiologists classification,preoperative anxiety,solid food fasting time,clear liquid fasting time,indwelling catheter,and pain level upon awakening are key predictors of EA in patients undergoing laparoscopic hernia surgery with total intravenous anesthesia and caudal block anesthesia.The nomogram predicts EA with an area under the receiver operating characteristic curve(AUC)of 0.947,a sensi-tivity of 0.917,and a specificity of 0.877,whereas the random forest model has an AUC of 0.923,a sensitivity of 0.912,and a specificity of 0.877.Delong’s test shows no significant difference in AUC between the two models.Clinical decision curve analysis indicates that both models have good net benefits in predicting EA,with the nomogram effective within the threshold of 0.02 to 0.96 and the random forest model within 0.03 to 0.90.In the external model validation of 50 cases of laparoscopic hernia surgery,both models predicted EA.The nomogram model had a sensitivity of 83.33%,specificity of 86.84%,and accuracy of 86.00%,while the random forest model had a sensitivity of 75.00%,specificity of 78.95%,and accuracy of 78.00%,suggesting that the nomogram model performs better in predicting EA.CONCLUSION Independent predictors of EA in patients undergoing laparoscopic hernia repair with total intravenous anesthesia combined with caudal block include American Society of Anesthesiologists classification,preoperative anxiety,duration of solid food fasting,duration of clear liquid fasting,presence of an indwelling catheter,and pain level upon waking.The nomogram and random forest models based on these factors can help tailor clinical decisions in the future.

Artificial intelligence and robotics in regional anesthesia

Artificial intelligence(AI)technology is vital for practitioners to incorporate AI and robotics in day-to-day regional anesthesia practice.Recent literature is encouraging on its applications in regional anesthesia,but the data are limited.AI can help us identify and guide the needle tip precisely to the location.This may help us reduce the time,improve precision,and reduce the associated side effects of improper distribution of drugs.In this article,we discuss the potential roles of AI and robotics in regional anesthesia.

Variational Approach to 2D and 3D Heat Conduction Modeling

The paper proposes an approximate solution to the classical (parabolic) multidimensional 2D and 3D heat conduction equation for a 5 × 5 cm aluminium plate and a 5 × 5 × 5 cm aluminum cube. An approximate solution of the generalized (hyperbolic) 2D and 3D equation for the considered plate and cube is also proposed. Approximate solutions were obtained by applying calculus of variations and Euler-Lagrange equations. In order to verify the correctness of the proposed approximate solutions, they were compared with the exact solutions of parabolic and hyperbolic equations. The paper also presents the research on the influence of time parameters τ as well as the relaxation times τ ∗ to the variation of the profile of the temperature field for the considered aluminum plate and cube.

Development and Optimization of Universal Bone Conduction Hearing Spectacles

Background: Non-implantable bone anchored hearing devices (BCHDs) are utilized for patients with conductive or mixed hearing loss who are unsuitable for conventional hearing aids or have unresolved middle ear issues. These devices can be surgically implanted or attached using adhesive plates, dental sticks, elastic headbands, or bone conduction spectacles. Optimal fitting of bone conduction spectacles requires appropriate frame selection and contact pressure in the temporal and mastoid areas. The ANSI S3.6 and DIN EN ISO 389-3 standards recommend a contact area of approximately 1.75 cm2 and a maximum force of 5.4 N for effective sound transmission and comfort. Methods: This study aimed to evaluate the technical fit and mechanical stability of universal bone conduction hearing spectacles compared to established systems. A Sen-Pressure 02 thin-film sensor connected to an Arduino Uno R3 board measured contact force in the temporal and mastoid areas. Several BCHDs were tested, including the Bruckhoff la belle BC D50/70, Radioear B71 headset, Radioear B71 elastic headband, Cochlear Baha SoundArc M, and Cochlear Baha elastic headband, on a PVC artificial head, with data analyzed using ANOVA and LSD post hoc tests. Results: The la belle BC D50/70 spectacles showed comparable contact force to established BCHDs, ensuring adequate sound transmission and comfort. Significant differences were observed between the systems, with the Radioear B71 headset exhibiting the highest forces. The la belle BC D50/70 had similar forces to the Radioear B71 elastic headband. Conclusion: The la belle BC D50/70 universal bone conduction hearing spectacles are a technically equivalent alternative to established BCHDs, maintaining pressure below 5.4 N. Future research should explore the impact of different contact forces on performance and comfort, and the integration of force control in modified spectacles. This study indicates that the la belle BC D50/70 is a viable alternative that meets audiological practice requirements.

Observation of the Effects of Anesthesia Recovery Nursing Combined with Heat Preservation Measures in Patients Undergoing General Anesthesia Surgery

Objective:To observe the application effects of anesthesia recovery nursing with heat preservation measures in patients undergoing general anesthesia surgery.Methods:300 cases of general anesthesia surgery patients in our hospital from March 2023 to February 2024 were selected and divided into the control group and the observation group according to the random number table method,each with 150 cases.The control group adopted conventional care,while the observation group was given anesthesia recovery care and heat preservation measures on the basis of conventional care.The wake-up time,extubation time,hospitalization time,and the incidence of adverse reactions were compared between the two groups and statistically analyzed.Results:The wake-up time of patients in the control group was 9.71±1.20 hours,and that of the observation group was 6.51±1.02 hours,with statistically significant differences(P<0.05);the extubation times of patients in the observation group and the control group after awakening were 8.52±0.41 min and 10.42±1.12 min,respectively,with statistically significant differences(P<0.05)The hospital stay after the operation in the observation group and the control group was 32.91±4.71 days and 37.24±3.34 days respectively,and the difference was statistically significant(P<0.05),and the incidence rate of adverse reactions after extubation in the observation group(3.33%)was significantly lower than that in the control group(10.00%)(P<0.05).Conclusion:In general anesthesia surgery patients,the implementation of anesthesia recovery nursing with heat preservation measures can significantly improve the physical condition of patients,effectively shorten the duration of surgery and patients’wake-up time,and improve their quality of life,which is worthy of clinical promotion and application.

Safety and efficacy comparison of remimazolam and propofol for intravenous anesthesia during gastroenteroscopic surgery of older patients:A meta-analysis

BACKGROUND Remimazolam is characterized by rapid action and inactive metabolites.It is used as the general anesthetic for many clinical surgeries.In this study,we performed a meta-analysis to evaluate whether remimazolam is superior to propofol for gastroenteroscopy in older patients.AIM To compare the adverse events and efficacy of remimazolam and propofol during gastroenteroscopy in older adults.METHODS The PubMed,Web of Science,the Cochrane Library databases were queried for the relevant key words"remimazolam,""and propofol,""and gastrointestinal endoscopy or gastroscopy."The search scope was"Title and Abstract,"and the search was limited to human studies and publications in English.Seven studies wherein remimazolam and propofol were compared were included for the metaanalysis.RESULTS We selected seven randomized controlled trials involving 1445 cases for the analysis.Remimazolam reduced the hypotension(relative risk,RR=0.44,95%CI:0.29-0.66,P=0.000),respiratory depression(RR=0.46,95%CI:0.30-0.70,P=0.000),injection pain(RR=0.12,95%CI:0.05-0.25,P=0.000),bradycardia(RR=0.37,95%CI:0.24-0.58,P=0.000),and time to discharge[weighted mean difference(WMD)=-0.58,95%CI:-0.97 to-0.18,P=0.005],compared to those after propofol administration.No obvious differences were observed for postoperative nausea and vomiting(RR=1.09,95%CI:0.97-1.24,P=0.151),dizziness(RR=0.77,95%CI:0.43-1.36,P=0.361),successful sedation rate(RR=0.96,95%CI:0.93-1.00,P=0.083),or the time to become fully alert(WMD=0.00,95%CI:-1.08-1.08,P=0.998).CONCLUSION Remimazolam appears to be safer than propofol for gastroenteroscopy in older adults.However,further studies are required to confirm these findings.

In vivo imaging reveals a synchronized correlation among neurotransmitter dynamics during propofol and sevoflurane anesthesia

General anesthesia is widely applied in clinical practice.However,the precise mechanism of loss of consciousness induced by general anesthetics remains unknown.Here,we measured the dynamics of five neurotransmitters,includingγ-aminobutyric acid,glutamate,norepinephrine,acetylcholine,and dopamine,in the medial prefrontal cortex and primary visual cortex of C57BL/6 mice through in vivo fiber photometry and genetically encoded neurotransmitter sensors under anesthesia to reveal the mechanism of general anesthesia from a neurotransmitter perspective.Results revealed that the concentrations of γ-aminobutyric acid,glutamate,norepinephrine,and acetylcholine increased in the cortex during propofol-induced loss of consciousness.Dopamine levels did not change following the hypnotic dose of propofol but increased significantly following surgical doses of propofol anesthesia.Notably,the concentrations of the five neurotransmitters generally decreased during sevoflurane-induced loss of consciousness.Furthermore,the neurotransmitter dynamic networks were not synchronized in the non-anesthesia groups but were highly synchronized in the anesthetic groups.These findings suggest that neurotransmitter dynamic network synchronization may cause anesthetic-induced loss of consciousness.

The neuroscience of pain,addiction,and anesthesia

Researchers and clinicians have long been interested in the mechanisms of pain,anesthesia,and addiction.The International Association for the Study of Pain(IASP)defines pain as an unpleasant sensory and emotional experience associated with,or resembling that associated with,actual or potential tissue damage(Raja et al.,2020).Drug addiction refers to a condition of reliance that develops from regular drug consumption,which may lead to withdrawal symptoms when use is halted.Anesthesia involves the complete loss of consciousness induced by an inhaled or intravenous anesthetic(Tosello et al.,2022).In this special collection,Zoological Research presents research findings focused on pain,addiction,and anesthesia.

Anesthesia,Anesthetics,and Postoperative Cognitive Dysfunction in Elderly Patients

Postoperative cognitive dysfunction(POCD)remains a major issue that worsens the prognosis of elderly surgery patients.This article reviews the current research on the effect of different anesthesia methods and commonly utilized anesthetics on the incidence of POCD in elderly patients,aiming to provide an understanding of the underlying mechanisms contributing to this condition and facilitate the development of more reasonable anesthesia protocols,ultimately reducing the incidence of POCD in elderly surgery patients.

Pharmacokinetic Characterization of Xylazine in Goats with Simultaneous Anesthesia Studies

The aim was to study the pharmacokinetics of xylazine as a stable anesthetic in goats.In this study,goats were injected with xylazine at the rate of 0.3 mL·kg-1 intramusculally,and blood samples were collected at 1,3,5,10,20,30,45,60,90,120,180,and 240 min after administration,respectively.Xylazine was extracted by liquid-liquid extraction and separation method,and blood concentration was determined by high performance liquid chromatography(HPLC).The pharmacokinetic characteristics of xylazine in healthy goats were analyzed by pharmacokinetic software.The results showed that the chromatographic peak time of xylazine chromatography was 9-11 min.The specificity of the method was good.The linear correlation coefficient R2 of the standard curve was 0.9982 when the concentration of xylazine was in the range of 10-1×1000 ng.The pharmacokinetic model of xylazine in goats was a one-chamber model with first-order rate absorption,distribution half-life t1/2Ka was(0.49±0.041)min,elimination half-life t1/2Ke was(23.3±2.5)min,and the peak time(Tp)of the highest concentration was(2.8±0.2)min.The total drug clearance CL/F was(0.00016±0.000016)mg·kg-1·min-1(ng·mL-1),and the minimum effective blood concentration was 56.6 ng·mL-1,which was consistent with the clinical anesthetic effect.The results showed that xylazine had the characteristics of rapid absorption,wide distribution,short peak time,slow clearance rate,and long anesthetic time in goats,which could be used as the basic drug for the development of goat complex anesthetic preparation.

Its application could therefore reduce morbidity and mortality and improve patient-practitioner comfort in the event of MVA for incomplete abortion following the dosage precision it provides.

Pain perception enhancement in consecutive secondeye phacoemulsification cataract surgeries under topical anesthesia

Cataract is the main cause of visual impairment and blindness worldwide while the only effective cure for cataract is still surgery.Consecutive phacoemulsification under topical anesthesia has been the routine procedure for cataract surgery.However,patients often grumbled that they felt more painful during the second-eye surgery compared to the first-eye surgery.The intraoperative pain experience has negative influence on satisfaction and willingness for second-eye cataract surgery of patients with bilateral cataracts.Intraoperative ocular pain is a complicated process induced by the nociceptors activation in the peripheral nervous system.Immunological,neuropsychological,and pharmacological factors work together in the enhancement of intraoperative pain.Accumulating published literatures have focused on the pain enhancement during the secondeye phacoemulsification surgeries.In this review,we searched PubMed database for articles associated with pain perception differences between consecutive cataract surgeries published up to Feb.1,2024.We summarized the recent research progress in mechanisms and interventions for pain perception enhancement in consecutive secondeye phacoemulsification cataract surgeries.This review aimed to provide novel insights into strategies for improving patients’intraoperative experience in second-eye cataract surgeries.

Obstetric Anesthesia Practice Significantly Evolved: A Field for Cesarean Delivery Parturient for the Provision of Safe Anesthesia in Urgent Circumstances

General anesthesia and Obstetric Anesthesia is the gold standard for a cesarean section but there are some cases where general anesthesia is unavoidable. The use of general anesthesia for cesarean delivery has decreased in recent years due to the widespread use of neuraxial techniques. The choice of anesthesia techniques for cesarean delivery depends on several factors, including the patient’s psychology and the attending physician’s experience. It is chosen because of its safety profile and its benefits to the mother and fetus. It may be indicated due to emergency, maternal refusal of regional techniques, or regional contraindications. Major complications include failed intubation, gastric content aspiration, and increased bleeding risk. This study aims to evaluate the impact of a newly launched team on obstetric anesthesia practice.

Regional Block Anesthesia in Breast Surgery: What Do We Know So Far?

Breast cancer is the most prevalent cancer in women worldwide, and pain following mastectomy is a major post-surgical complication. This paper highlights the risk factors for chronic pain in breast surgery and evaluates various regional block techniques used to reduce post-operative pain, and minimize hospital stays in high-risk patients. Further research is needed to evaluate the effectiveness of novel regional anaesthesia techniques in an enhanced recovery context, and to assess their role in preventing or reducing chronic pain.

Current evidence on artificial intelligence in regional anesthesia

The recent advancement in regional anesthesia(RA)has been largely attributed to ultrasound technology.However,the safety and efficiency of ultrasound-guided nerve blocks depend upon the skill and experience of the performer.Even with adequate training,experience,and knowledge,human-related limitations such as fatigue,failure to recognize the correct anatomical structure,and unintentional needle or probe movement can hinder the overall effectiveness of RA.The amalgamation of artificial intelligence(AI)to RA practice has promised to override these human limitations.Machine learning,an integral part of AI can improve its performance through continuous learning and experience,like the human brain.It enables computers to recognize images and patterns specifically useful in anatomic structure identification during the performance of RA.AI can provide real-time guidance to clinicians by highlighting important anatomical structures on ultrasound images,and it can also assist in needle tracking and accurate deposition of local anesthetics.The future of RA with AI integration appears promising,yet obstacles such as device malfunction,data privacy,regulatory barriers,and cost concerns can deter its clinical implementation.The current mini review deliberates the current application,future direction,and barrier to the application of AI in RA practice.

Management of Square Carcinoma of the Lower Lip Using Camille-Bernard Flap under Local Anesthesia: When Constraints Dictate Our Attitude

Introduction: Squamous cell carcinomas of the lip essentially pose a therapeutic management problem. In the West, their treatment is done under general anesthesia and follows the classic rules of oncology. In our context of exercise, we sometimes have a different attitude dictated by various constraints. Observation: 55-year-old patient with no notable history, seen in consultation for a very large ulcerative-budding lesion on the right 2/3 of the lower lip with mucocutaneous involvement without lymph node findings found on examination. Faced with this suspicious lesion and the patient’s financial difficulties, we decided to operate under local anesthesia to remove this tumor. The oncological excision was followed by immediate plasty using a Camille-Bernard flap with a good immediate aesthetic and functional result and postoperative day 7. The patient was unable to take his surgical specimen to anatomy-pathology and was lost to follow-up due to lack of financial resources. On anatomo-pathological analysis of the surgical specimen, the margins were healthy with confirmation of squamous cell carcinoma (anapathological reading made for scientific interest). Discussion: The particular mentality of certain patients and their difficult financial conditions push us to have an unconventional therapeutic attitude in oncology, but which nevertheless makes it possible to resolve certain problems that we often face. Local anesthesia is possible and realistic in cases like ours and the results can be acceptable and life-saving.
