Experience of epidural blood patch for post-dural puncture headache.
Post-dural puncture headache is a common outcome following either spinal or epidural anesthesia. Cases were collected within five years' period (1988-1992) in Keelung Chang Gung Memorial Hospital. Those cases with relief of post-dural puncture headache after conservative treatment were excluded. ⋯ Effective rate was 98.15% upon single blood patch. Repeated blood patch was done in 3 cases. No complication was noted.

Randomized Controlled Trial Clinical TrialPropofol modifies recovery from isoflurane-nitrous oxide anesthesia.
A randomized, prospective study was performed to evaluate the hemodynamic changes and recovery characteristics in 60 ASA physical status class I-II unpremedicated patients undergoing gynecological laparotomies with either isoflurane anesthesia only (ISO group) or isoflurane anesthesia followed by propofol infusion (ISO-PRO group). All patients received isoflurane 0.5-1.5% and nitrous oxide (N2O) 66% in oxygen after tracheal intubation. ISO-PRO group (n = 30) received 6 mg kg-1 hr-1 propofol infusion in substitution for isoflurane 25 minutes before the end of surgery. ⋯ ISO-PRO group had better Steward's score on arrival at the recovery room and was earlier to get a full score of six. The two groups experienced similar rates of emesis and excitement either two hours or 24 hours postoperatively. We conclude that in relatively long intra-abdominal operations, replacement of isoflurane by propofol infusion 25 minutes before the end of surgery may provide stable maintenance of anesthesia and a faster recovery.

The hemodynamic effects of continuous intravenous infusion of propofol at higher rates.
The new formula of propofol was introduced in 1985. Because of its characteristics of rapid onset and elimination, it was often used as a drug of induction and maintenance of total intravenous anesthesia. However, the hemodynamic effects of propofol was still controversial. ⋯ The infusion rates of propofol were 10 mg/kg/hr during the first 30 minutes and 8 mg/kg/hr during the following 30 minutes, norcuron, 0.1 mg/kg initially and 1 mg for maintenance after 30 minutes. Normal saline was infused 1000 to 1500 ml in study period to maintain higher preload. Post induction hemodynamic data were collected at the 5th, 15th, 30th, 60th min after induction.(ABSTRACT TRUNCATED AT 250 WORDS)

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)
