Randomized Controlled Trial Clinical TrialEffects of magnesium sulfate pretreatment on succinylcholine-facilitated tracheal intubation.
Magnesium sulfate may prevent increase in serum potassium produced by succinylcholine and cause transient hypotension. The present study was designed to evaluate the effect of magnesium sulfate on heart rate, blood pressure and hyperkalemic response following succinylcholine injection during tracheal intubation. Twenty patients, ASA class I-II, scheduled for elective surgery were equally and randomly allocated to two groups. ⋯ Heart rate, blood pressure, venous and arterial potassium levels were measured at 1, 3, 5 and 10 minutes after intubation. The results showed that magnesium sulfate could attenuate the hypertensive response at 1 minute and the hyperkalemic response at 1 and 3 minutes following succinylcholine-facilitated intubation; the tachycardiac response at 1 minute after intubation could not be reduced by this agent. We concluded that bolus infusion of magnesium sulfate may be of help in reducing the hypertensive response during laryngoscopy and intubation.

Outcome of surgery and anesthesia in patients 80 years of age and older.
We studied retrospectively the outcome of surgery and anesthesia in 294 patients aged 80 and older who underwent 362 surgical procedures. Of these, 52 cases (14.4%) were admitted to intensive care unit (ICU) post-operatively. The 48-hour, 48-hour-to-30-day and overall mortality rates were 0.8%, 3.8% and 5.2% respectively. ⋯ Only 2.5% (7 cases) of cases who underwent extra-pleural and extra-peritoneal procedures required controlled ventilation for more than 24 hours post-operatively. Of these, 2 died subsequently. For comparison, the study were artificially divided into two phases, each of three years long: they were the period from 1986-1988 and the period from 1989-1992.(ABSTRACT TRUNCATED AT 250 WORDS)

Liver is the largest organ and is located in the right upper quadrant of the abdominal cavity. Surgery for liver transplantation is performed through a large skin incision, which gives considerable pain post operatively. We experienced 10 cases of liver transplant, 3 cases used meperidine 0.5 mg/kg intramuscularly, 3 cases used epidural morphine analgesia, and for the remainder 4 cases, we used morphine 2-3 mg intravenously as needed. ⋯ Patients in all three groups were equally satisfied with their analgesic therapy post-operatively. As all patients expect pain after surgery, they were satisfied when the pain was less than what they had anticipated. Blood gases analysis was however better in patients with epidural morphine analgesia.

Randomized Controlled Trial Clinical TrialThe effect of heated humidifier in the prevention of intra-operative hypothermia.
Unintentional hypothermia is common in patients undergoing "routine anesthesia in surgery". The aims of the study were to estimate the difference of changes of body temperature during abdominal and limb operations and to evaluate the effectiveness of the heated humidifier for reducing intraoperative heat loss. Forty-three patients were randomly being allocated into 3 groups. ⋯ Warming and humidifying the inspired gas effectively reduced the heat loss. We concluded that abdominal operation induce hypothermia more than limb operation. The use of heated humidifier was effective in maintaining body temperature.

Comparative Study[Comparison of double-lumen endobnonchial versus single-lumen endotracheal tube anesthesia in bilateral thoracoscopic sympathectomy].
Since the development of video endoscopic surgery, the number of transthoracic endoscopic sympathectomy has been increasing. The use of double-lumen endobronchial tube or single-lumen endobronchial tube during anesthesia for these surgeries has been a controversial. 385 palmar hyperhidrosis patients divided into three groups: group I, under alterative one lung ventilation anesthesia with double-lumen endobronchial tube; group II, under alterative one lung ventilation anesthesia with single-lumen endobronchial tube; group III, under two lung ventilation anesthesia with single-lumen endobronchial tube were studied. All had received bilateral thoracoscopic sympathectomy. ⋯ The average anesthesia durations for group I, II and III were 38.56 +/- 10.28, 34.14 +/- 5.21, 31.83 +/- 3.34 min respectively. The variables considered in the study were: physique of the patients; duration of anesthesia; airway pressure changes; SaO2 changes during the operation and post-anesthesia complaints. We found that upon using double-lumen endobronchial tube, SaO2 levels was better maintained especially in the obese patients and the patients who had received a traditional surgical operation before.
