ABSTRACT
Duchenne's muscular dystrophy (DMD) is the most common and severe form of myopathy. Patients with DMD are more sensitive to sedative, anesthetic, and neuromuscular blocking agents which may result in intraoperative and early postoperative cardiovascular and respiratory complications, as well as prolonged recovery from anesthesia. In this case report, we describe a 25-year-old male patient admitted for cholecystectomy under general anesthesia. We induced our anesthesia by oxygen, propofol, fentanyl, and rocuronium bromide. Maintenance was done by fentanyl, rocuronium bromide, sevoflurane, and O2. We report in this case the safety use of sugammadex to antagonize the neuromuscular block and rapid recovery in such category of patients.
ABSTRACT
Background. The obese patients have differences in body composition, drug distribution, and metabolism. Sugammadex at T 2 recovery in a dose of 2 mg kg(-1) of real body weight (RBW) can completely reverse the NMB block; in our study we investigated the safety and efficacy of Sugammadex dose based on their ideal body weight (IBW). Methods. 40 patients of both sexes undergoing laparoscopic bariatric surgery were enrolled divided into 2 groups according to the dose of Sugammadex: the first received a dose of 2 mg kg(-1) of IBW and the second received a dose of 2 mg kg(-1) of RBW. Both were anesthetized with doses calculated according to the IBW: fentanyl 2 µ g kg(-1), propofol 3 mg kg(-1), rocuronium 0,6 mg kg(-1), oxygen, air, and desflurane (6-8%). Maintenance doses of rocuronium were 1/4 of the intubation dose. Sugammadex was administrated at T 2 recovery. Results. The durations of intubation and maintenance doses of rocuronium were similar in both groups. In IBW group, the T 4/T 1 value of 0.9 was reached in 151 ± 44 seconds and in 121 ± 55 seconds in RBW group (P = 0.07). Discussion. Recovery times to T 4/T 1 of 0.9 are surprisingly similar in both groups without observing any postoperative residual curarization. Conclusion. Sugammadex doses calculated according to the IBW are certainly safe for a rapid recovery and absence of PORC.
ABSTRACT
Introduction. It is a consensus that the postoperative cognitive function is impaired in elderly patients after general anaesthesia, and such category patient takes more time to recover. Xenon is a noble gas with anesthetic properties mediated by antagonism of N-methyl-D-aspartate receptors. With a minimum alveolar concentration of 0.63, xenon is intended for maintaining hypnosis with 30% oxygen. The fast recovery after xenon anaesthesia was hypothesized to be advantageous in this scenario. Case Presentation. We report the case of 99-year-old woman who underwent sigmoid colon carcinoma resection with colorectal anastomosis. We carried out the induction phase by propofol, oxygen, fentanil, and rocuronium bromide, and then we proceeded to a rapid sequence endotracheal intubation consequently. The patient was monitored by IBP, NIBP, ECG, cardiac frequency, respiratory rate, capnometry, TOF Guard, blood gas analysis, and BIS. For maintenance we administrated oxygen, remifentanil, rocuronium bromide, and xenon gas 60-65%. Shortly after the end of surgery the patients started an autonomous respiratory activity, and a high BIS level was also recorded. Decision was made by our team to proceed into the emergence phase. The residual neuromuscular block was antagonized by sugammadex, modified Aldrete score was implicated, and we got our patient fully awake without any cognitive dysfunction or delirium. Conclusion. The rapid emergence to full orientation in very elderly patient who had been anesthetized by xenon shows concordance to the high BIS values and the clinical signs of the depth of anesthesia.
