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.展开更多

Approximately 20% of AAWR cases occur during emergence from anesthesia. Clinically, these unexpected experiences are often associated with distress especially due to a sense of paralysis. Indeed, although AAWR at the emergence has multiple causes, in the majority of cases the complication develops when the anesthesia plan is too early lightened at the end of anesthesia and there is a lack of use, or misuse, of neuromuscular monitoring with improper management of the neuromuscular block. Because the distress caused by the sense of paralysis represents an important predictor for the development of severe psychological complications, the knowledge of the phenomenon, and the possible strategies for its prophylaxis are aspects of considerable importance. Nevertheless, a limited percentage of episodes of AAWR cannot be prevented. This paradox holds also during the emergence phase of anesthesia which represents a very complex neurophysiological process with many aspects yet to be clarified.展开更多

Methods： Sixty patients were randomly divided into 4 groups： In the control group patients were given saline; in the lidocaine group patients were given 1.0 mg/kg lidocaine ; in the diltiazem group patients were given 0. 2 mg/kg diltiazem; and in the lidocaine plus diltiazem group patients were given 1.0 mg/kg lidocaine and 0. 2 mg/kg diltiazem. These drugs were given 2 rain before tracheal extuhation. Values for SBP, DBP, and HR were recorded, on arriving at the operating room, immediately at the end of the surgery, at the time of injection of the study drugs, at tracheal extubation, at 1 min and 5 min after extubation. The quality of extubation according to the Sebel＇s grading scale were compared among the 4 groups. Results：During extubation in the control group HR, SBP and DBP increased significantly when compared to baseline levels. Both lidocaine （1.0 mg/kg） and diltiazem （0. 2 mg/kg） successfully alleviated these increases. The suppressive effect of diltiazem was greater than that of lidocaine. The combinative use of the two drugs minimized the increases. The administration of lidocaine significantly suppressed bucking or coughing compared with the other groups. Conclusions： The pressor responses and tachycardia occurring in patients with uvulopalatopharyngoplasty during emergence from anesthesia and tracheal extubation, can be easily blocked by a bolus dose of 1.0 mg/kg lidocaine, 0. 2 mg/kg diltiazem or the comhinative use of the two drugs. And the concurrent use of lidocaine and diltiazem alleviated the hemodynamic changes more obviously.展开更多
