Randomized Controlled Trial Clinical Trial
Epidural opioids during laminectomy surgery for postoperative pain.
To determine whether morphine applied directly to the dura during laminectomy surgery provides superior postoperative analgesia during the first 24 hours. ⋯ Morphine 3 mg applied topically to the dura at the end of laminectomy surgery is a simple, safe, and effective way of providing improved postoperative analgesia.

Factors influencing epidural catheter migration.
The incidence and amount of migration of epidural catheters was investigated in a prospective randomised study of 153 women who required analgesia in labour. Inward or outward migration occurred in 36% of patients. Inward migration by 1-3 cm occurred in 21 (13.7%) patients and outward migration by 1 cm or more occurred in 34 (22.2%); three (2%) catheters migrated out through the skin. ⋯ However, the pattern of problems was different. All cases of failed epidural block occurred in patients whose epidural catheter migrated outward by 2.5 cm or more. Unilateral blockade was not more likely if migration of 1 cm or more occurred.

Cardiovascular responses to fiberoptic intubation: a comparison of orotracheal and nasotracheal intubation.
We compared the cardiovascular responses between nasal and oral intubation with a fiberoptic bronchoscope under the combination of neuroleptic analgesia (NLA) and topical anesthesia. The 16 patients studied were divided into 2 groups: the nasal intubation group (N group: 8 patients) and the oral intubation group (O group: 8 patients). There were significant changes in systolic, diastolic and mean arterial pressures in the N group and in the pressure rate quotient in the O group. ⋯ The individual RPP in both groups was relatively stable except for one patient in the N group, who had a marked increase in RPP during the procedure. We conclude that, under the combination of NLA and topical anesthesia, the cardiovascular responses to oral fiberoptic intubation are less severe than those to the nasal approach. The oral approach is recommended, especially in patients with coronary artery disease, taking into consideration of the cardiovascular responses to fiberoptic intubation.

Prospective, controlled, double-blind study of i.v. tenoxicam for analgesia after thoracotomy.
We have shown that a single i.v. dose of tenoxicam 20 mg, after thoracotomy, when compared with placebo in 20 patients (with one exclusion), was associated with a reduction in consumption of papaveretum, assessed by patient-controlled analgesia, of 2.2 mg h-1 (22%) to 4 h and 1.4 mg h-1 (23%) to 12 h after operation (repeated measures analysis of variance: P less than 0.01). There was no reduction from 12 to 24 h. There was no significant difference between groups in pain scores or in side effects.
