Randomized Controlled Trial Comparative Study Clinical TrialAbdominal nerve blockade for postoperative analgesia after caesarean section.
A prospective study of blocking T10-L1 with local anaesthetic, bilaterally in 30 patients undergoing caesarean section under general anaesthesia has been shown to provide effective postoperative analgesia thus requiring significantly less narcotics (mean 66.6 mg of pethidine) compared to the 30 patients in the control group (mean 163 mg of pethidine). A cocktail of 0.5% of bupivacaine with adrenaline and xylocaine 1% produced analgesia for the duration ranging from 8 to 12 hours (mean 8.4 hours). Patients with abdominal field block were awake, alert and comfortable during the immediate postoperative period. They were pain-free sufficiently to put the babies to the breast early and frequently.

Beside the procedures to ensure adequate ventilatory and circulatory support, analgesia, sedation and even anesthesia are essential parts of the preclinical treatment of patients with multiple injuries. The measures for extrication and positioning must be adjusted to minimize pain and excitation. ⋯ The therapy must take into account the special conditions concerning the patient, material and assisting personnel by choosing suitable techniques. The best results can be obtained if all kinds of measures can be administered from the site of the accident on up to the definitive care in the operating room.

Randomized Controlled Trial Comparative Study Clinical TrialEquivalence of postoperative analgesia with patient-controlled intravenous or epidural alfentanil.
The analgesia and the frequency and severity of oxyhemoglobin desaturation related to alfentanil administration were compared in 32 patients randomly selected to receive patient-controlled analgesia (PCA) by either the epidural (EPI) or intravenous (i.v.) route for a mean period of 16 h after major abdominal surgery. Bolus increments of 250 micrograms of alfentanil with a lockout interval of 5 min for i.v. and of 10 min for EPI route were administered by a programmable pump. Oxygen saturation (SpO2) was monitored for 16 h, using a pulse oximeter; data were collected continuously and stored every 30 s via an interface connected to a computer. ⋯ The effects on SpO2 were not statistically different between the two groups. Cumulative time spent in each saturation category was similar for the EPI and i.v. groups. Severe desaturation episodes, defined as SpO2 < or = 85% for at least 60 s, occurred in 69% of patients in the EPI group and 56% in the i.v. group.(ABSTRACT TRUNCATED AT 250 WORDS)
