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.

Application value of dexmedetomidine in anesthesia for elderly patients undergoing radical colon cancer surgery

BACKGROUND Colon cancer presents a substantial risk to the well-being of elderly people worldwide.With advancements in medical technology,surgical treatment has become the primary approach for managing colon cancer patients.However,due to age-related physiological changes,especially a decline in cognitive function,older patients are more susceptible to the effects of surgery and anesthesia,increasing the relative risk of postoperative cognitive dysfunction(POCD).There-fore,in the surgical treatment of elderly patients with colon cancer,it is of pa-ramount importance to select an appropriate anesthetic approach to reduce the occurrence of POCD,protect brain function,and improve surgical success rates.METHODS One hundred and seventeen patients with colon cancer who underwent elective surgery under general anesthesia were selected and divided into two groups:A and B.Group A received Dex before anesthesia induction,and B group received an equivalent amount of normal saline.Changes in the mini-mental state exami-nation,regional cerebral oxygen saturation(rSO2),bispectral index,glucose uptake rate(GluER),lactate production rate(LacPR),serum S100βand neuron-specific enolase(NSE),POCD,and adverse anesthesia reactions were compared between the two groups.RESULTS Surgical duration,duration of anesthesia,and intraoperative blood loss were comparable between the two groups(P>0.05).The overall dosage of anesthetic drugs used in group A,including propofol and remifentanil,was significantly lower than that used in group B(P<0.05).Group A exhibited higher rSO2 values at the time of endotracheal intubation,30 min after the start of surgery,and immediately after extubation,higher GluER values and lower LacPR values at the time of endotra-cheal intubation,30 min after the start of surgery,immediately after extubation,and 5 min after extubation(P<0.05).Group A exhibited lower levels of serum S100βand NSE 24 h postoperatively and a lower incidence of cognitive dysfunction on the 1st and 5th postoperative days(P<0.05).CONCLUSION The use of Dex in elderly patients undergoing radical colon cancer surgery helps maintain rSO2 Levels and reduce cerebral metabolic levels and the incidence of anesthesia-and surgery-induced cognitive dysfunction.

New Progress in the Cause Analysis and Nursing of Respiratory Tract Infection after Abdominal Surgery under General Anesthesia

This article provides a review of the causes of respiratory tract infection after abdominal surgery. These causes include general anesthesia, intubation factors, factors inherent to the patient, surgical factors, the injudicious use of antimicrobial agents, and the environmental factors of the ward. The perioperative management of the respiratory tract should be strengthened. Health education, respiratory function training, oral nursing intervention,atomization inhalation, and personalized expectoration methods should receive more attention to decrease the complications and promote the early rehabilitation of patients after abdominal surgery.

(4) Hemodynamics: there was no significant difference in HR and MAP between the two groups during T1, HR and MAP in T2 were lower than those in T1, but the level of each indicator in the study group was higher than that in the control group. (5) Adverse Reactions: the incidence of adverse reactions was lower in the study group (10.53%) than in the control group (28.95%). Conclusion: The application of ultrasound guided early breast cancer modified radical block complex general anesthesia thoracic vertebra, can reduce the dosage of anesthetic drugs, shorten the PACU, residence time, reduce postoperative pain, maintain stable hemodynamic state, inhibiting inflammatory reaction caused by surgical trauma degree, and can reduce the incidence of adverse reactions, and has safety.

Association between anesthesia technique and complications after hip surgery in the elderly population

BACKGROUND Spinal anesthesia is superior to general anesthesia for postoperative recovery in older patients(≥65 age).However,evidence for this is lacking.AIM To evaluate the effect of anesthesia on postoperative complications in older patients undergoing hip surgery.METHODS This is a retrospective,propensity score-matched,cohort study.Patients≥65-years-old who underwent hip surgery at the Traditional Chinese Medicine of Guangdong Provincial Hospital in China from October 2016 to June 2020 were included.The operative methods were femoral fracture’s internal fixation and hip replacement.The orthopedic doctors in different hospitals of our group have varied requirements for patients’out-of-bed time after surgery.Therefore,spinal anesthesia or general anesthesia was selected according to the requirements of the orthopedic doctors.The primary outcome of this study was complications during the hospitalization of the postoperative patient.The length of hospital stay,postoperative blood transfusion,routine blood analysis,renal function,coagulation function,and inflammatory correlations were secondary outcomes.Propensity score matching(PSM)was performed utilizing logistic regression.RESULTS Among the 864 patients identified from the electronic medical record data database,we screened out those with incomplete medical record data.After PSM of the baseline values of the two groups of patients,data of 309 patients(206 patients in spinal anesthesia group and 103 patients in general anesthesia)were utilized in this study.67/309 patients had complications,including postoperative limb dysfunction,pulmonary infection,delirium,lower extremity venous thrombosis,and shock.The incidence of complications was not related to anesthesia methods(P>0.05),but the levels of D-Dimer(P=0.017),fibrinogen(P=0.005),and high-sensitivity C-reactive protein(hs CRP)(P=0.002)in the spinal anesthesia group were significantly higher than those in the general anesthesia group.CONCLUSION Anesthesia technology is not a risk factor for postoperative complications of hip surgery.The levels of D-Dimer and hs CRP were higher in the spinal anesthesia group.

Application of early enteral nutrition nursing based on enhanced recovery after surgery theory in patients with digestive surgery

BACKGROUND Postoperative nursing can improve the restlessness and gastrointestinal function of patients with tracheal intubation under general anesthesia in digestive surgery.Wide application of various nursing methods and routine nursing in periop-erative nursing of patients with general anesthesia in digestive surgery.AIM To investigate the impact of early postoperative enteral nutrition nursing based on the enhanced recovery after surgery(ERAS)theory on postoperative agitation and gastrointestinal recovery in patients undergoing general anesthesia that experienced tracheal intubation.METHODS The data of 126 patients with digestive surgery from May 2019 to February 2022 were retrospectively analyzed.According to different nursing methods,they were divided into control group and observation group,with 63 cases in observation group and 63 cases in control group.The patients in the control group had standard perioperative nursing care,whereas those in the observation group got enteral nourishment as soon as possible after surgery in accordance with ERAS theory.Both the rate and quality of gastrointestinal function recovery were compared between the two groups after treatment ended.Postoperative anes-thesia-related adverse events were tallied,patients'nutritional statuses were monitored,and the Riker sedation and agitation score(SAS)was used to measure the incidence of agitation.RESULTS When compared to the control group,the awake duration,spontaneous breathing recovery time,extubation time and postoperative eye-opening time were all considerably shorter(P<0.05).There was no significant difference in the recovery time of orientation force between the two groups(P>0.05);however,the observation group had a lower SAS score than the control group(P<0.05).The recovery time for normal intestinal sounds,the time it took to have the first postoperative exhaust,the time it took to have the first postoperative defecation,and the time it took to have the first postoperative half-fluid feeding were all faster in the observation group than in the control group(P<0.05);Fasting blood glucose was lower in the observation group compared to the control group(P<0.05),while the albumin and hemoglobin levels were higher on the first and third postoperative days;however,there was no statistically significant difference in the incidence of anesthesia-related adverse reactions between the two groups(P>0.05).CONCLUSION The extremely early postoperative enteral nutrition nursing based on ERAS theory can reduce the degree of agitation,improve the quality of recovery,promote the recovery of gastrointestinal function,and improve the nutritional status of patients in the recovery period after tracheal intubation under general anesthesia.

Identification of independent risk factors for intraoperative gastroesophageal reflux in adult patients undergoing general anesthesia

BACKGROUND Gastroesophageal reflux(GER)affects up to 20%of the adult population and is defined as troublesome and frequent symptoms of heartburn or regurgitation.GER produces significantly harmful impacts on quality of life and precipitates poor mental well-being.However,the potential risk factors for the incidence and extent of GER in adults undergoing general anesthesia remain unclear.AIM To explore independent risk factors for the incidence and extent of GER during general anesthesia induction.METHODS A retrospective study was conducted,and 601 adult patients received general anesthesia intubation or laryngeal mask surgery between July 2016 and January 2019 in Shanghai General Hospital of Nanjing Medical University.This study recruited a total of 601 adult patients undergoing general anesthesia,and the characteristics of patients and the incidence or extent of GER were recorded.The potential risk factors for the incidence of GER were explored using multivariate logistic regression,and the risk factors for the extent of GER were evaluated using multivariate linear regression.RESULTS The current study included 601 adult patients,82 patients with GER and 519 patients without GER.Overall,we noted significant differences between GER and non-GER for pharyngitis,history of GER,other digestive tract diseases,history of asthma,and the use of sufentanil(P<0.05),while no significant differences between groups were observed for sex,age,type of surgery,operative time,body mass index,intraoperative blood loss,smoking status,alcohol intake,hypertension,diabetes mellitus,psychiatric history,history of respiratory infection,history of surgery,the use of lidocaine,palliative strategies,propofol,or rocuronium bromide,state anxiety inventory,trait anxiety inventory,and selfrating depression scale(P>0.05).The results of multivariate logistic regression indicated that female sex[odds ratio(OR):2.702;95%confidence interval(CI):1.144-6.378;P=0.023],increased age(OR:1.031;95%CI:1.008-1.056;P=0.009),pharyngitis(OR:31.388;95%CI:15.709-62.715;P<0.001),and history of GER(OR:11.925;95%CI:4.184-33.989;P<0.001)were associated with an increased risk of GER,whereas the use of propofol could protect against the risk of GER(OR:0.942;95%CI:0.892-0.994;P=0.031).Finally,age(P=0.004),operative time(P<0.001),pharyngitis(P<0.001),history of GER(P=0.024),and hypertension(P=0.017)were significantly associated with GER time.CONCLUSION This study identified the risk factors for GER in patients undergoing general anesthesia including female sex,increased age,pharyngitis,and history of GER.

Endovascular Abdominal Aortic Aneurysm Repair under General Anesthesia Does Not Decrease Perioperative Myocardial Ischemic Events Compared with Open Repair

Objectives: Endovascular abdominal aortic aneurysm repair (EVAR) is a common procedure for abdominal aortic aneurysm (AAA), based on minimal invasiveness compared with open surgical repair (OSR). However, general anesthesia can cause considerable perturbations in patients with AAA undergoing operative repair. The aim of this study was to compare the incidence of myocardial ischemic events in association with hemodynamic changes during EVAR and OSR under general anesthesia. Methods: We retrospectively reviewed the anesthetic and medical records of patients who underwent elective abdominal aortic aneurysm repair. ST segment changes on electrocardiography and hemodynamic changes were reviewed by the attending physicians. Results: Among 120 patients, EVAR and OSR were performed in 81 and 39 patients, respectively. There were no significant differences in preoperative morbidity between the two groups. The amount of estimated blood loss was significantly lower in EVAR than OSR. The incidence of ST?segment changes in the two groups (EVAR: 16%, OSR: 23%) was not statistically different. ST segment changes occurred mainly postoperatively at resolution of anesthesia in EVAR, compared with intraoperatively in OSR. ST segment changes were mostly accompanied by tachycardia in EVAR patients, whereas they were associated with hypotension in OSR. Conclusion: Our results demonstrated a comparable incidence of perioperative ST segment changes under general anesthesia in EVAR and OSR. Patients who undergo EVAR and develop tachycardia are at risk of myocardial ischemia at resolution of anesthesia.

Combined Sciatic-Lumbar Plexus Block with General Anesthesia: Efficacy in Preventing Tourniquet-Induced Hemodynamic Changes

Background: Pneumatic arterial tourniquet is a utilized strategy in limb surgeries to provide bloodless field to facilitate surgical procedure. Be that as it may, arterial tourniquet has numerous injurious impacts including hemodynamic changes and tourniquet-induced pain which sometimes can be severe and intolerable. Objectives: Our primary aim was to assess the impact of performing “Lumbar Plexus Block and sciatic nerve block” with General Anesthesia (GA) on the degree of arterial tourniquet-induced hemodynamic effects. On the other hand, our secondary aims were: amount of postoperative analgesic prerequisites, patient satisfactory score and documented side effects. Settings and Design: Ain Shams University, Orthopedic operating theatre;a prospective, randomized, double-blind study. Methods and Material: The physical status of 50 patients (both sexes) including I and II patients from American Society of Anesthesiologists, whose ages are from 20 - 40 years, is not so ideal when they are undergoing elective knee Arthroscopy. The duration lasts no more than ninety minutes under GA with application of tourniquet. Patients were allotted haphazardly to one of two groups. In Group C (Control group): Only GA. In Group B: LPB and sciatic nerve block were performed just before GA administration. Intraoperative hemodynamics was recorded at specific timings. Results: Incidence of tourniquet induced hypertension (TIH) was markedly less with Group B at: forty five, sixty, seventy five mins after tourniquet inflation and just before tourniquet deflation. Also, the total ketorolac consumption during first 24 hours of postoperative period was significantly less with Group B (p Conclusions: Combined Sciatic-Lumbar plexus blocks when combined with general anesthesia were very effective in attenuating TIH.

Conclusion:Application of general anesthesia in gynecological surgery, can significantly reduce the blood viscosity of patients, but will increase the heart rate and blood pressure and blood E, NE and COS levels, therefore, during the operation, the patient's signs should be monitored comprehensively and closely.

Effects of propofol versus urapidil on perioperative hemodynamics and intraocular pressure during anesthesia and extubation in ophthalmic patients

AIM: To compare the effect of propofol versus urapidil on hemodynamics and intraocular pressure during anesthesia and extubation for ophthalmic patients. METHODS: Eighty-two surgical patients (Class: ASA I-II) were randomly assigned to propofol (n = 41) and urapidil groups (n = 41). Their gender, age, body mass, operation time and dosage of anesthetics had no significant difference between the two groups (P > 0.05). The patients of propofol and urapidil groups were given propofol (1.5mg/kg) and urapidil (2.5mg/kg) respectively; and two drugs were all diluted with normal saline to 8mL. Then the drugs were given to patients by slow intravenous injection. After treatment, the patients were conducted immediate suction, tracheal extubation, and then patients wore oxygen masks for 10 minutes. By double-blind methods, before the induction medication, at the suction, and 5, 10 minutes after the extubation, we recorded the systolic and diastolic blood pressure (BP), heart rate (HR), pH, PaO2, PaCO2, SaO(2) and intraocular pressure (TOP) respectively. The complete recovery time of the patients with restlessness (on the command they could open eyes and shaking hands) was also recorded during the extubation. The data were analyzed by using a professional SPSS 15.0 statistical software. RESULTS: The incidence of cough, restlessness and glossocoma was significantly lower in the propofol group than that in the urapidil group after extubation (P < 0.05). There were no episodes of hypotension, laryngospasm, or severe respiratory depression. There was no statistical difference in recovery time between two groups (P > 0.05). In propofol group, the BP and HR during extubation and thereafter had no significant difference compared with those before induction, while they were significantly lower than those before giving propofol (P < 0.05), and had significant difference compared with those in urapidil group (P < 0.05). Compared to preinduction, the BP of urapidil group showed no obvious increase during aspiration and extubation. The HR of urapidil group had little changes after being given urapidil, and it was obviously increased compared with that before induction. The stimulation of aspiration and extubation caused less cough and agitation in propofol group than that in urapidil group (P < 0.05). The IOP of propofol group showed no obvious increase during extubation compared with that in preinduction, while in the urpidil group, extubation caused IOP significantly increased (P < 0.05). The changes in these indicators between the two groups had no significant difference (P > 0.05). CONCLUSION: Compared to urapidil, propofol is superior for preventing the cardiovascular and stress responses and IOP increases during emergence and extubation for the ophthalmic patients. Moreover, it has no effects on patient's recovery.

Anesthesia for ambulatory surgery in a child with hyposensitivity to pain

Congenital hyposensitivity to pain is a condition with predisposition to injury. In these patients, knowledge regarding anesthetic requirements and complications derives from individual case reports, or small case series. Different categories have been described. In patients with hyposensitivity to pain, preventing and treating anxiety as well as insuring immobilization, avoidance of triggering of autonomic reflexes, and sedation are integral aspects for a safe and adequate anesthetic management.

Dextrose in the banked blood products does not seem to affect the blood glucose levels in patients undergoing liver transplantation

AIM: Hyperglycemia commonly seen in liver transplantation (LT) has often been attributed to the dextrose in the storage solution of blood transfusion products. The purpose of the study is to compare the changes of the blood glucose levels in transfused and non-transfused patients during LT. METHODS: A retrospective study on 60 biliary pediatric patients and 16 adult patients undergoing LT was carried out. Transfused pediatric patients were included in Group Ⅰ (GⅠ), those not transfused in Group Ⅱ (GⅡ). Twelve adult patients were not given transfusion and assigned to Group Ⅲ(GⅢ); whereas, four adult patients who received massive transfusion were assigned to Group Ⅳ (GⅣ). The blood glucose levels, volume of blood transfused, and the volume of crystalloid infused were recorded, compared and analyzed. RESULTS: Results showed that the changes in blood glucose levels during LT for both non-transfused and minimally transfused pediatric groups and non-transfused and massively-transfused adult groups were almost the same. CONCLUSION: We conclude that blood transfusion does not cause significant changes in the blood glucose levels in this study.

Application of remimazolam transversus abdominis plane block in gastrointestinal tumor surgery

BACKGROUND Transversus abdominis plane block(TAPB)is a block of the abdominal afferent nerve fibers between the internal oblique muscle and the transverse abdominal muscle achieved with local anesthetics.It can effectively block the conduction of the anterior nerve of the abdominal wall and exert a good analgesic effect.However,the effect of combining the block with remimazolam on anesthesia in patients undergoing gastrointestinal tumor surgery is still unclear.AIM To examine the effects of combining TAPB with remimazolam on the stress response and postoperative recovery of gastrointestinal tumor surgery patients.METHODS A retrospective analysis was conducted on the clinical data of 102 individuals diagnosed with gastrointestinal malignancies who underwent laparoscopic surgery under general anesthesia between April 2020 and June 2023.The patients were categorized into a control group(n=51),receiving remimazolam for general anesthesia,and an observation group(n=51),receiving TAPB combined with remimazolam for general anesthesia.A comparison was made between both groups in terms of hemodynamic parameters,stress markers,pain levels,recovery quality,analgesic effects,and adverse reactions during the perioperative period.RESULTS The observation group had significantly higher heart rates at time points 1 min after induction and upon leaving the operating room than the control group(P<0.05).The mean arterial pressure at time point T1 in the observation group was significantly higher than that in the control group(P<0.05).Five minutes after extubation,the levels of the hormones adrenaline and noradrenaline in the observation group were considerably lower than those in the control group(P<0.05).At 12 h,24 h,and 48 h following surgery,the visual analog scale scores of the observation group were considerably lower than those of the control group(P<0.05).The observation group had shorter awakening and extubation times and lower Riker sedation-agitation scale scores than the control group(P<0.05).The observation group exhibited considerably fewer effective pump presses,lower fentanyl dosages,and lower incidences of rescue analgesia within 24 h following surgery than the control group(P<0.05).CONCLUSION The application effect of TAPB combined with remimazolam general anesthesia in anesthesia of patients undergoing gastrointestinal tumor surgery is good,which is helpful to promote faster recovery after operation.

An adult case of isolated unilateral pulmonary agenesis under general anesthesia

Pulmonary agenesis is a rare congenital malformation of unknown etiology that is defined as the complete absence of the bronchus,lung parenchyma,and pulmonary vasculature.The exact incidence of this rare abnormality is not known but is believed to range from 0.003 4% to 0.009 7%.1 Pulmonary agenesis affects men and women almost equally.Left sided agenesis is more common.More than half of the reported cases are associated with anomalies involving cardiovascular,gastrointestinal,skeletal,and urogenital systems and patients die within the first five years of life.Although some cases are compatible with long-term survival and normal growth,completely symptom free and well tolerated surgery is extremely rare.Here we present a case of congenital left lung agenesis in an adult woman tolerating general anesthesia well for modified radical mastectomy.
