Desflurane Allows for a Faster Emergence When Compared to Sevoflurane without Affecting the Baseline Cognitive Recovery Time.

ABSTRACT: AIMS:We compared the effect of desflurane and sevoflurane on anesthesia recovery time in patients undergoing urological cystoscopic surgery. The Short Orientation-Memory-Concentration Test (SOMCT) measured and compared cognitive impairment between groups and coughing was assessed throughout the anesthetic. METHODS AND MATERIALS:This investigation included 75 ambulatory patients. Patients were randomized to receive either desflurane or sevoflurane. Inhalational anesthetics were discontinued after removal of the cystoscope and once repositioning of the patient was final. Coughing assessment and awakening time from anesthesia were assessed by a blinded observer. STATISTICAL ANALYSIS USED:Statistical analysis was performed by using t-test for parametric variables and Mann-Whitney U test for non-parametric variables. RESULTS:The primary endpoint, mean time to eye-opening, was 5.0?±?2.5?min for desflurane and 7.9?±?4.1?min for sevoflurane (p?

Project description:BackgroundAn increasing number of studies have concluded that the number of adverse events in the upper airway caused by desflurane does not differ significantly from the number of adverse events caused by sevoflurane. The advantages of desflurane in ambulatory surgery should be reassessed.ObjectivesThe aim of this study was to compare adverse respiratory events and recovery outcomes in patients undergoing desflurane or sevoflurane-based anaesthesia in ambulatory surgery.DesignA systematic review and meta-analysis of randomised controlled trials (RCTs).Data sourcesA systematic search for eligible RCTs in PubMed, Medline, Cochrane Central Register of Controlled Trials, ScienceDirect and Embase published up to June 2019.Eligibility criteriaRCTs investigating the occurrence of adverse respiratory events, including airway irritation, stridor, coughing, respiratory distress and laryngospasm, emergence agitation, postoperative nausea and vomiting (PONV), time to eye opening and time to discharge from the operation room after desflurane or sevoflurane-based anaesthesia.ResultsThirteen trials were included and analysed. A total of 634 patients were included in the desflurane group, and 633 patients in the sevoflurane group. The occurrence of respiratory complications was significantly higher with desflurane-based anaesthesia than with sevoflurane-based anaesthesia (Total n = 673, 20.0 vs. 12.8%, relative risk (RR) 1.59 (95% CI 1.15 to 2.20)) with low heterogeneity (I = 20%). There was no difference in the occurrence of emergence agitation (Total n = 626, 29.1 vs. 27.2%, RR 1.05 (95% CI 0.84 to 1.30)) or the incidence of PONV between the desflurane and sevoflurane groups (Total n = 989, 19.0 vs. 21.0%, RR 0.95 (95% CI 0.71 to 1.26)). Time to eye opening was significantly faster with desflurane than that with sevoflurane (Total n = 1072, mean difference = -3.32 min (95% CI -4.02 to -2.61)) with a substantial heterogeneity (I = 72.6%). There was no significant difference in the time to discharge from the operation room between the two groups (Total n = 1056, mean difference = -0.45 min (95% CI -5.89 to 4.99)).ConclusionDespite recent reports that there is no significant difference in adverse respiratory events between desflurane and sevoflurane, a pooled analysis revealed that desflurane resulted in a higher rate than sevoflurane. Therefore, the consequences of desflurane should not be neglected and its airway irritant properties should be taken into account.Trial registrationPROSPERO (CRD42019147939).

Project description:BackgroundThe differences in the incidence and severity of emergence agitation (EA) and emergence times between desflurane and sevoflurane anesthesia have not been as clearly elucidated in children as in adults.MethodsThe design of the study is a systematic review with meta-analysis of randomized controlled trials. The study methodology is based on the Cochrane Review Methods. A comprehensive literature search was conducted to identify clinical trials comparing the incidence or severity of EA and emergence times in children anesthetized with desflurane or sevoflurane. Two reviewers independently assessed each study according to predefined inclusion criteria and extracted data from each study using a prespecified data extraction form. The data from each study were combined using a fixed effect or random effect model to calculate the pooled risk ratio (RR) or standardized mean difference (SMD) and 95% confidence interval (CI). Funnel plots were used to assess publication bias. Subgroup and sensitivity analyses were performed.ResultsFourteen studies met the inclusion criteria. Among the 1196 patients in these 14 studies, 588 received desflurane anesthesia and 608 received sevoflurane anesthesia. The incidence of EA was comparable between the 2 groups (pooled RR = 1.21; 95% CI: 0.96-1.53; I = 26%), and so was the severity of EA (EA score) between the 2 groups (SMD = 0.12; 95% CI: -0.02 to 0.27; I = 0%). Extubation and awakening times were shorter in the desflurane group than in the sevoflurane group; the weighted mean differences were -2.21 (95% CI: -3.62 to -0.81; I = 93%) and -2.74 (95% CI: -3.80 to -1.69; I = 85%), respectively. No publication bias was found in the funnel plot. The subgroup analysis based on the type of EA scale showed a higher incidence of EA in the desflurane group than in the sevoflurane group in studies using 3-, 4-, or 5-point EA scales; the pooled RR was 1.38 (95% CI: 1.10-1.73; I = 37%).ConclusionThe incidence and severity of EA were comparable between desflurane and sevoflurane anesthesia in children; however, emergence times, including extubation and awakening times, were shorter in desflurane anesthesia.

Project description:As life expectancy increases, more patients ?65 years undergo general anesthesia. Anesthetic agents may contribute to postoperative cognitive dysfunction, and incidence may differ with anesthetic agents or intraoperative anesthesia depth. Responses to anesthetic adjuvants vary among elderly patients. Processed electroencephalography guidance of anesthetic may better ensure equivalent cerebral suppression. This study investigates postoperative cognitive dysfunction differences in elderly patients given desflurane or sevoflurane using processed electroencephalography guidance.IRB approved, randomized trial enrolled consenting patients ?65 years scheduled for elective surgery requiring general anesthesia ?120 minute duration. After written informed consent, patients were randomly assigned to sevoflurane or desflurane. No perioperative benzodiazepines were administered. Cognitive impairment was measured by an investigator blinded to group assignment using mini-Mental Status Examination (MMSE) at baseline; 1, 6, and 24 hours after the end of anesthesia. Mean arterial pressure was maintained within 20% of baseline. Anesthetic dose was adjusted to maintain moderate general anesthesia per processed electroencephalograpy (Patient State Index 25 to 50). The primary outcome measure was intergroup difference in MMSE change 1 hour after anesthesia (median; 95% confidence interval).110 patients consented; 26 were not included for analysis (no general anesthesia; withdrew consent; baseline MMSE abnormality; inability to perform postoperative MMSE; data capture failure); 47 sevoflurane and 37 desflurane were analyzed. There were no significant differences in patient characteristics; intraoperative mean blood pressure (desflurane 86.4; 81.3 to 89.6 versus sevoflurane 82.5; 80.2 to 86.1 mmHg; p?=?0.42) or Patient State Index (desflurane 41.9; 39.0 to 44.0 versus sevoflurane 41.0; 37.5 to 44.0; p?=?0.60) despite a lower MAC fraction in desflurane (0.82; 0.77 to 0.86) versus sevoflurane (0.96; 0.91 to 1.03; p?<?0.001). MMSE decreased 1 hour after anesthesia (p?<?0.001). The decrease at one hour was larger in sevoflurane (-2.5; -3.3 to -1.8) than desflurane (-1.3; -2.2 to -0.5; p?=?0.03). MMSE returned to baseline by 6 hours after anesthesia.For elderly patients in whom depth of anesthesia is maintained in the moderate range, both desflurane and sevoflurane are associated with transient decreases in cognitive function as measured by MMSE after anesthesia, with clinically insignificant differences between them in this setting.ClinicalTrials.gov NCT01199913.
