Anesthesia with sevoflurane in bariatric surgery.

BACKGROUND: Sevoflurane is a good halogen agent for bariatric surgery anesthesia because of its physical and chemical characteristics and its repartition coefficient (blood/gas = 0.65). METHOD: From November 1997 to April 1998, 98 bariatric surgery procedures with sevoflurane anesthesia were done: 17 lipectomies, 71 vertical gastroplasties, and 10 biliopancreatic diversions in 71 women and 27 men, average age 30.3+/-8.3 years, with body mass index 43.9+/-5.7. The average operating time was 50+/-15 minutes for vertical gastroplasty, 160+/-20 minutes for biliopancreatic diversion, and 80+/-12 minutes for lipectomy. The technique of anesthesia was as follows: preanesthesia with atropine sulfate 0.01 mg/kg (dosage refers to ideal weight), ranitidine 50 mg, fentanyl 0.1 mg, ketorolac 60 mg; induction with propofol 0.5-1 mg/kg, succinylcholine 1 mg/kg; orotracheal intubation; maintenance with O2-N2O 50%, sevoflurane 1% to 1.5%, actracurium 0.5 mg/kg (dosage refers to ideal weight); awakening and decurarization with atropine sulfate 1 mg and prostigmine 2 mg. RESULTS: This method permitted correct control of the anesthesia, a quick awakening with a low incidence of nausea and vomiting, a prompt regain of physical and psychological functioning, an early discharge from the hospital, and a larger turnover of patients with lower costs. CONCLUSION: Sevoflurane balanced anesthesia seems to be the best anesthesiologic method for bariatric surgery.

[Isolated postoperative myoglobinuria as the only sign of malignant hyperthermia. Value of spinal anesthesia with bupivacaine in a posterior surgical intervention].

The Authors report a case of biopsy-proven malignant hyperthermia in a pediatric patient who underwent general anesthesia with halothane and succinylcholine for foot surgery, in whom the presenting symptom was isolated postoperative myoglobinuria. The above syndrome, in the absence of a positive family history, may present itself with a set of minor and atypical symptoms, thus being often underestimate. The need for further investigating all the cases of postoperative myoglobinuria is stressed by the Authors, which also consider muscular biopsy for inclusion among routine investigations. In the case reported here, six months later, a new surgical operation was done safely with spinal anesthesia using hyperbaric bupivacaine.

[Use of atracurium for the prevention of fasciculations and succinylcholine myalgia in athletes undergoing orthopedic surgery].

The Authors report their clinical experience about the use of atracurium besylate in preventing succinylcholine-induced fasciculations and postoperative myalgias in fifty athletes (ASA class 1), submitted to arthroscopic meniscectomy. The patients were pretreated with atracurium 5 mg i.v. or saline solution in a double-blind fashion. After 2.5 minutes, succinylcholine 1.3 mg/kg was administered, and fasciculations were recorded on a scale ranging from 0 to 3. Twenty-four hours after surgery all subjects were questioned about myalgias occurrence, scored by a 0-3 scale. Fasciculations occurred in all patients who received saline and in 44% of those treated with atracurium. Myalgias on the postoperative day were observed in 80% of patients treated with saline solution, but only in 36% of patients who received atracurium. The difference between atracurium and saline solution was statistically significant (p less than 0.001) either for fasciculations or myalgias incidence. These findings show that atracurium 5 mg i.v. is effective in preventing succinylcholine-induced fasciculations and postoperative myalgias, and suggest atracurium as the drug of choice for this purpose, particularly in muscular subjects.

[Atracurium besylate versus succinylcholine during laparoscopy].

The authors report their experience with 112 female patients undergoing laparoscopy: they have been divided into two groups according to the drug used for muscle relaxation (atracurium versus succinylcholine). During the procedure the following parameters were recorded: intraabdominal pressure, arterial pressure, heart rate, arterial blood oxygen saturation, end tidal CO2 and the occurrence of adverse effects. According to the collected data they assume that atracurium can be considered the ideal muscle relaxant for this surgical procedure.

[The use of doxapram chlorohydrate (t-doxapril) as an anti-shivering drug].

Following a brief review of the main causes of anaesthetic shock, reference is made to the results obtained with the use of a well-known analeptic: doxapram chlorohydrate, as an anti-shock drug. Using a continuous venous perfusion technique, practically no side-effects were encountered, while the effectiveness of the drug was of undoubted interest (75% of cases). The hypothesis of the anti-shock action remains open.
