Randomized Controlled Trial Comparative Study Clinical Trial[Comparative study of conventional spinal anesthesia and combined spinal-epidural anesthesia in gynecological surgery].
A prospective study was carried out to compare the qualities of spinal block with those of combined spinal-epidural anaesthesia (CSEA). It included 63 patients, ranked ASA 1 or 2, aged between 35 and 75 years, scheduled for gynaecological surgery due to last more than 2 hours, and randomly allocated to two groups. In the first group (n = 34), spinal anaesthesia was carried out with the patients sitting, in the L3-4 interspace, using 15 mg of hyperbaric bupivacaine with 0.4 mg of adrenaline. ⋯ In the CSEA group, excellent analgesia was obtained in all patients. Sensory blockade lasted 308 +/- 48 min at the T12 level, versus 162 +/- 51 min in the spinal group (p < 0.025), and 361 +/- 51 min at the L2 level, versus 210 < 44 min in the other group (p < 0.025). "Topping up" was possible with the epidural catheter only, thus raising the level of sensory blockade, making it deeper, and increasing its duration. It avoids the use of general anaesthesia in case of failed spinal blockade.(ABSTRACT TRUNCATED AT 250 WORDS)

[EMLA analgesic cream for venopuncture during anesthetic induction in children].
A prospective study was designed to assess the quality of skin analgesia provided by the EMLA anaesthetic cream, an eutectic mixture of local anaesthetics (prilocaine and lidocaine). The children, aged 3 months to 15 years, and scheduled for genital and urinary surgery, were allocated to two groups, those aged less than or equal to 5 years (35 +/- 14 months, n = 17), and those aged greater than 5 years (97 +/- 26 months, n = 22). The cream (1.6 +/- 0.6 g) was applied by a nurse in the ward as a thick layer on the area of skin to be anaesthetised (on the dorsum of the hand and at the elbow), and covered by a closed adhesive dressing. ⋯ The children aged less than or equal to 5 years complained of pain of intensity 7.5 +/- 2.2 (CHEOPS scale, range 4 to 13) and, for those aged greater than 5 years, 24 +/- 21 on a visual analogic scale (range 0 to 100). Local adverse effects occurred in ten patients (skin paleness, erythema, or both). It was concluded that EMLA cream provides convenient analgesia for venepuncture in toddlers and children.

Review Randomized Controlled Trial Clinical Trial[Prevention of postoperative nausea and vomiting by ondansetron].
This study was carried out to assess the efficacy of oral ondansetron, a new 5HT3 receptor antagonist, in patients undergoing thyroid surgery. It included 60 patients, randomly assigned to two groups, and receiving orally, 1 h before induction of anaesthesia, either 8 mg of ondansetron (n = 29) or a placebo (n = 30). One patient was excluded. ⋯ The differences between the groups were statistically significant: p = 0.025 for nausea and p = 0.042 for vomiting. It is concluded that oral ondansetron, 8 mg taken orally 1 h before surgery, significantly reduces the incidence of nausea and vomiting during the first twelve postoperative hours. As it is easy to use and has no side-effects, it might be of interest in day-case surgery patients, despite its high cost.
