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.

Clinical practice of early extubation after liver transplantation

BACKGROUND: Anesthetic practices such as early tracheal extubation facilitate postoperative recovery. Early extubation after liver transplantation has been adopted by some centers in the recent two decades. No universal clinical guidelines are used and questions remain. This review aimed to address the current status of early extubation after liver transplantation. DATA SOURCES: A literature search of MEDLINE and ISI Web of Knowledge databases was performed using terms such as liver transplantation, early extubation, immediate tracheal extubation fast tracking or fast track anesthesia and postoperative tracheal extubation. Additional papers were identified by a manual search of the references in the key articles. RESULTS: Review of the available literature provided an insight into the definition, evolution, advantages and risks of early extubation, and anesthetic techniques that prompt early extubation in liver transplant patients. Early extubation has proved to be feasible and safe in these patients, but the outcomes are still uncertain. CONCLUSIONS: Early extubation after liver transplantation is feasible, safe and cost-effective in the majority of patients and has been increasingly accepted as an option for conventional postoperative ventilation. Comprehensive and individualized evaluation of the patient’s condition before extubation by an experienced anesthesiologist is the cornerstone of success Understanding of its effect on the outcome remains incomplete In the future, additional trials are required to establish universal early extubation guidelines and to determine its benefits for patients and practitioners.

High-flow nasal cannula oxygen therapy and noninvasive ventilation for preventing extubation failure during weaning from mechanical ventilation assessed by lung ultrasound score: A single-center randomized study

BACKGROUND: We sought to demonstrate the superiority of a targeted therapy strategy involving high-flow nasal cannula oxygen(HFNCO_(2)) therapy and noninvasive ventilation(NIV) using lung ultrasound score(LUS) in comparison with standard care among patients in the intensive care unit(ICU) who undergo successful weaning to decrease the incidence of extubation failure at both 48 hours and seven days.METHODS: During the study period, 98 patients were enrolled in the study, including 49 in the control group and 49 in the treatment group. Patients in the control group and patients with an LUS score <14 points(at low risk of extubation failure) in the treatment group were extubated and received standard preventive care without NIV or HFNCO_(2). Patients with an LUS score ≥14 points(at high risk of extubation failure) in the treatment group were extubated with a second review of the therapeutic optimization to identify and address any persisting risk factors for postextubation respiratory distress;patients received HFNCO2 therapy combined with sessions of preventive NIV(4-8 hours per day for 4-8 sessions total) for the first 48 hours after extubation.RESULTS: In the control group, 13 patients had the LUS scores ≥14 points, while 36 patients had scores <14 points. In the treatment group, 16 patients had the LUS scores ≥14 points, while 33 patients had scores <14 points. Among patients with the LUS score ≥14 points, the extubation failure rate within 48 hours was 30.8% in the control group and 12.5% in the treatment group, constituting a statistically significant difference(P<0.05). Conversely, among patients with an LUS score <14 points, 13.9% in the control group and 9.1% in the treatment group experienced extubation failure(P=0.61). The length of ICU stay(9.4±3.1 days vs. 7.2±2.4 days) was significantly different and the re-intubation rate(at 48 hours: 18.4% vs. 10.2%;seven days: 22.4% vs. 12.2%) significantly varied between the two groups(P<0.05). There was no significant difference in the 28-day mortality rate(6.1% vs. 8.2%) between the control and treatment groups.CONCLUSIONS: Among high-risk adults being weaned from mechanical ventilation and assessed by LUS, the NIV+HFNCO_(2) protocol does not lessen the mortality rate but reduce the length of ICU stay, the rate of extubation failure at both 48 hours and seven days.

Predictive value of the unplanned extubation risk assessment scale in hospitalized patients with tubes

BACKGROUND Critical patients often had various types of tubes,unplanned extubation of any kind of tube may cause serious injury to the patient,but previous reports mainly focused on endotracheal intubation.The limitations or incorrect use of the unplanned extubation risk assessment tool may lead to improper identification of patients at a high risk of unplanned extubation and cause delay or nonimplementation of unplanned extubation prevention interventions.To effectively identify and manage the risk of unplanned extubation,a comprehensive and universal unplanned extubation risk assessment tool is needed.AIM To assess the predictive value of the Huaxi Unplanned Extubation Risk Assessment Scale in inpatients.METHODS This was a retrospective validation study.In this study,medical records were extracted between October 2020 and September 2021 from a tertiary comprehensive hospital in southwest China.For patients with tubes during hospitalization,the following information was extracted from the hospital information system:age,sex,admission mode,education,marital status,number of tubes,discharge mode,unplanned extubation occurrence,and the Huaxi Unplanned Extubation Risk Assessment Scale(HUERAS)score.Only inpatients were included,and those with indwelling needles were excluded.The best cut-off value and the area under the curve(AUC)of the Huaxi Unplanned Extubation Risk Assessment Scale were been identified.RESULTS A total of 76033 inpatients with indwelling tubes were included in this study,and 26 unplanned extubations occurred.The patients’HUERAS scores were between 11 and 30,with an average score of 17.25±3.73.The scores of patients with or without unplanned extubation were 22.85±3.28 and 17.25±3.73,respectively(P<0.001).The results of the correlation analysis showed that the correlation coefficients between each characteristic and the total score ranged from 0.183 to 0.843.The best cut-off value was 21,and there were 14135 patients with a high risk of unplanned extubation,accounting for 18.59%.The Cronbach’sα,sensitivity,specificity,positive predictive value,and negative predictive value of the Huaxi Unplanned Extubation Risk Assessment Scale were 0.815,84.62%,81.43%,0.16%,and 99.99%,respectively.The AUC of HUERAS was 0.851(95%CI:0.783-0.919,P<0.001).CONCLUSION The HUERAS has good reliability and predictive validity.It can effectively identify inpatients at a high risk of unplanned extubation and help clinical nurses carry out risk screening and management.

A Comparative Study between Dexmedetomidine Alone versus Combined Low Dose of Dexmedetomidine and Lidocaine for the Hemodynamic Response to Endotracheal Extubation in Patient Undergoing Abdominal Surgery—A Prospective Randomized Controlled Study

Background: Tracheal extubation is related to many side effects of hemodynamic, especially for patients with comorbid states. The study compared the validity of dexmedetomidine 1 μg/kg and low combination dose of dexmedetomidine 0.5 μg/kg plus Lidocaine 1 mg/kg in softening hemodynamic stress response and estimated quality of extubation in study groups. Materials and Methods: The patients in our study, one hundred and fifty of both gender, ASA class I &II patients, aged 20 - 50 years old subject to elective abdominal operations under general anesthesia were allocated into three equal groups. Anesthetic technique was standardized. Before extubation by 10 minutes, the patients in Group N, D, and DL have given 0.9% normal Saline intravenous bolus infusion, dexmedetomidine 1 μg/kg and Dexmedetomidine 0.5 μg/kg, respectively within a 10-minute period. Before complete extubation by 90 seconds, in the three groups by syringe ten cc volumes and at time of extubation, Group N and D patients received 0.9% normal Saline intravenous bolus infusion, but in Group DL received Lidocaine 1 mg/kg then extubation completed. Heart rate (HR), Diastolic BP (DBP), Systolic BP (SBP), and Mean Arterial Pressure (MAP) were noted at baseline, at the reverse, extubation, 2, 4, 6, 8, 10 min and at the regular times after that for two hours. Extubation quality was assessed by extubation quality scale. Aldrete’s recovery score and Ramsay sedation score were also recorded and also any complications were noted and recorded. Results: All the hemodynamic parameters significantly elevated extubation and numerous periods of observation in the normal saline group than dexmedetomidine and dexmedetomidine plus Lidocaine group (p-value = 0.001). Response of tachycardia was seen in 41 (82%) in patients of N group, compared to 18 (36%) and 20 (40%) in D & DL group respectively (p = 0.001). Hypertensive response statistically significant noticed in 40 (80%) patients of N group, 9 (18%) of D group and 12 (24%) of DL group (p = 0.001). Tachycardia duration and the response of hypertension were significantly prolonged in the control group. As regards extubation quality, the three groups differed in D Groups (1.93 ± 0.57) and DL (1.51 ± 0.57) had decreased scores compared to group N (2.67 ± 0.48) modulating smoother extubation (p Conclusion: Low combined dose of (Dexmedetomidine 0.5 μg/kg plus Lidocaine 1 mg/kg) IV was useful as much as Dexmedetomidine 1 μg/kg IV in softening hemodynamic stress responses during emergence.

A high performance adaptive on-time controlled valley-current-mode DC–DC buck converter

This paper presents an AOT-controlled(adaptive-on-time,AOT)valley-current-mode buck converter for portable application.The buck converter with synchronous rectifier not only uses valley-current-mode control but also possesses hybridmode control functions at the same time.Due to the presence of the zero-current detection circuit,the converter can switch freely between the two operating modes without the need for an external mode selection circuit,which further reduces the design difficulty and chip area.The converter for the application of high power efficiency and wide current range is used to generate the voltage of 0.6–3.0 V with a battery source of 3.3–5.0 V,while the load current range is 0.05–2 A.The circuit can work in continuous conduction mode with constant frequency in high load current range.In addition,a stable output voltage can be obtained with small voltage ripple.In pace with the load current decreases to a critical value,the converter transforms into the discontinuous conduction mode smoothly.As the switching period increases,the switching loss decreases,which can significantly improve the conversion efficiency.The proposed AOT controlled valley current mode buck converter is integrated with standard 0.18μm process and the simulation results show that the converter provides well-loaded regulations with power efficiency over 95%.When the circuit switches between the two conduction modes drastically,the response time can be controlled within 30μs.The undershoot voltage is controlled within 25 mV under a large current hopping range.

Fast Track Extubation Post Coronary Artery Bypass Graft: A Retrospective Review of Predictors of Clinical Outcomes

Introduction: Fast track (FT) cardiac surgery and early extubation (EE) are aimed at safe and effective rapid post-operative progression to discharge, and have been practiced for more than two decades. Their goal is to optimize patient care perioperatively in order to decrease costs without negatively affecting morbidity and mortality. However, the factors that predict successful EE are poorly understood, and patients with significant co-morbidities are frequently excluded from protocols. We hypothesize that independent of disease severity, early extubation leads to shorter hospital stays and can be performed safely without negatively affecting outcomes. Materials and Methods: We performed a retrospective review of 919 patients who underwent coronary artery bypass grafting (CABG) at the Southern Arizona Veteran’s Affairs Health Care System medical center over 7 years. We collected pre-operative data regarding patients’ NYHA classification, presence and severity of cerebral vascular disease, peripheral vascular disease, pulmonary disease, diabetes and hypertension. Intra-operative variables were also recorded including ASA scores, ischemic times, and time to extubation. Finally, post-operative variables such as rates of reintubation and tracheotomy, and both length of ICU and total hospital stay were also compared. Results: Prolonged periods of ischemia were found to predict a delayed extubation (HR = 0.992;CI = 0.988 - 0.997, p = 0.0015) while small body surface area (HR = 1.57;CI = 1.13, 2.17, p = 0.007) and higher pre-operative functional status of the patient, such as independent versus dependent status (HR =1.68;CI = 1.30 - 2.16, p = 1.33;CI = 1.03 - 1.70, p = 0.03) were found to be associated with earlier extubation. The early extubation (EE) group (those extubated in less than the median 7.3 hours) had an average hospital stay of 5.1 ± 4.0 days, versus 7.8 ± 8.1 days in the delayed group (>4 hours), p Conclusions: In our study population, pre-operative functional class and total body surface area predicted those patients able to tolerate early extubation after cardiac surgery. Prolonged ischemia resulted in delayed extubation. Patients that were extubated in less than 4 hours had shorter ICU and hospitalization stays, while there was no significant difference between the two groups in rate of reintubation or tracheotomy.

Negative Pressure Pulmonary Edema on Extubation of a 9-Month-Old Baby Boy

Background: Negative Pressure Pulmonary Edema (NPPE) is an uncommon, but well recognized clinical entity that continues to be reported as a complication of upper airway obstructions during induction or emergence. It results from the negative intrathoracic pressure generated with spontaneous ventilation with concurrent upper airway obstruction. Aim: To present an unusual case of NPPE and review the pathophysiology and treatment. Case: It usually occurs in young healthy athletic adults. We are reporting NPPE in a nine-month-old ex-premature baby. We discuss his intraoperative events leading to NPPE, subsequent intraoperative course and treatment. Conclusion: NPPE needs to be promptly recognized and treated. If the edema resolves, the patient can be successfully extubated, but should be observed overnight.

Implementation of a nurse-led protocol for early extubation after cardiac surgery: A pilot study

BACKGROUND Protocols for nurse-led extubation are as safe as a physician-guided weaning in general intensive care unit(ICU).Early extubation is a cornerstone of fast-track cardiac surgery,and it has been mainly implemented in post-anaesthesia care units.Introducing a nurse-led extubation protocol may lead to reduced extubation time.AIM To investigate results of the implementation of a nurse-led protocol for early extubation after elective cardiac surgery,aiming at higher extubation rates by the third postoperative hour.METHODS A single centre prospective study in an 18-bed,consultant-led Cardiothoracic ICU,with a 1:1 nurse-to-patient ratio.During a 3-wk period,the protocol was implemented with:(1)Structured teaching sessions at nurse handover and at bed-space(all staff received teaching,over 90%were exposed at least twice;(2)Email;and(3)Laminated sheets at bed-space.We compared“standard practice”and“intervention”periods before and after the protocol implementation,measuring extubation rates at several time-points from the third until the 24th postoperative hour.RESULTS Of 122 cardiac surgery patients admitted to ICU,13 were excluded as early weaning was considered unsafe.Therefore,109 patients were included,54 in the standard and 55 in the intervention period.Types of surgical interventions and baseline left ventricular function were similar between groups.From the third to the 12th post-operative hour,the intervention group displayed a higher proportion of patients extubated compared to the standard group.However,results were significant only at the sixth hour(58%vs 37%,P=0.04),and not different at the third hour(13%vs 6%,P=0.33).From the 12th post-operative hour time-point onward,extubation rates became almost identical between groups(83%in standard vs 83%in intervention period).CONCLUSION The implementation of a nurse-led protocol for early extubation after cardiac surgery in ICU may gradually lead to higher rates of early extubation.

Combined Echocardiography and Lung Ultrasound for Extubation Outcome Prediction in Children after Cardiac Surgery

Background:Children are at risk of extubation failure after congenital heart disease surgery.Such cases should be identified to avoid possible adverse consequences of failed extubation.This study aimed to identify ultrasound predictors of successful extubation in children who underwent cardiac surgery.Methods:Children aged 3 months to 6 years who underwent cardiac surgery(if they were intubated for>6 h and underwent a spontaneous breathing trial)were included in this study.Results:We included 83 children who underwent surgery for congenital heart disease.Transthoracic echocardiography and lung ultrasound were performed immediately before spontaneous breathing trials.Upon spontaneous breathing trial completion,respiratory parameters,including arterial blood gas analysis and frequency-to-tidal volume ratio,were similarly recorded.For outcome assessment,all children were followed up for 48 h after extubation.We successfully extubated 57 children(68.7%).These children were significantly older and weighed more but had shorter aortic cross-clamp and cardiopulmonary bypass times.Children who could not be weaned or extubated had prolonged total mechanical ventilation and pediatric intensive care unit stay.In the multivariate regression analysis,a lung ultrasound score≥12 and ejection fraction≥40%immediately before spontaneous breathing trials were the only independent predictors of successful extubation.When combined,the lung ultrasound score and an ejection fraction≥40%showed a better diagnostic performance than every other isolated variable(lung ultrasound,N-terminal-pro-B-type natriuretic peptide,and frequency-to-tidal volume ratio).Conclusions:The combination of lung ultrasound and transthoracic echocardiography immediately before the spontaneous breathing trial effectively predicts extubation outcomes in children after cardiac surgery.

【目的】探讨拔管力等因素是否是双腔气管插管术后咽喉痛的危险因素。【方法】这是一项随机对照试验的事后分析。本研究收集18~65岁,ASAI-Ⅲ级的双腔气管插管患者围术期资料,记录性别、年龄、吸烟史、导管直径、导管留置时间、舒芬太尼用量、是否使用氟比洛芬酯、是否拔管时呛咳等。拔管时使用测力计测量拔除导管所需的力。根据术后是否发生咽喉痛分为咽喉痛组和无咽喉痛组。对两组资料进行组间比较和多因素logistic回归分析,筛选术后咽喉痛的危险因素。使用ROC曲线预测危险因素的预测效应。【结果】最终纳入163例患者,拔管后30 min有74例(45.4%)患者发生术后咽喉痛,89例(54.6%)患者未发生术后咽喉痛。多因素logistic回归分析结果显示女性[OR95%CI=3.83(1.73,8.50),P=0.0001]和拔管力增大[OR95%CI=1.78(1.45,2.20),P<0.001]是术后咽喉痛的独立危险因素。拔管力预测术后咽喉痛的AUC曲线为0.773[95%CI(0.701,0.846),P<0.001];当约登指数为0.447时,拔管力的最佳临界点是13N。【结论】女性和拔管力是双腔气管插管全身麻醉术后咽喉痛的独立危险因素。
