Randomized Controlled Trial Comparative StudyCore temperatures during major abdominal surgery in patients warmed with new circulating-water garment, forced-air warming, or carbon-fiber resistive-heating system.
It has been reported that recently developed circulating-water garments transfer more heat than a forced-air warming system. The authors evaluated the hypothesis that circulating-water leg wraps combined with a water mattress better maintain intraoperative core temperature ≥36°C than either forced-air warming or carbon-fiber resistive heating during major abdominal surgery. ⋯ The combination of circulating-water leg wraps and a mattress better maintain intraoperative core temperature than did forced-air and carbon-fiber warming systems.

Nausea and vomiting after breast cancer surgery, and relationship with tumor receptor status.
Breast surgery is associated with frequent post-operative nausea and vomiting (PONV). Studies have suggested that hormonal status affects PONV. Estrogen has been implicated in many emetic syndromes. Estrogen receptor (ER) and progesterone receptor (PR) status in breast tissue are hormonally affected. Kakugawa et al., in 2007, found a clear trend toward higher serum level of estrone, estradiol, and dehydroepiandrosterone sulfate in post menopausal women with PR-positive cancer. ⋯ The incidence of PONV is higher for patients below 50 years of age. The positive association between ER positivity and PONV in patients above 50 years of age could be attributed to the altered hormonal milieu in these patients and should be investigated further.

Role of gabapentin in preventing fentanyl- and morphine-withdrawal-induced hyperalgesia in rats.
This study was undertaken to examine the effect of gabapentin for preventing hyperalgesia induced by morphine and fentanyl withdrawal in rats. ⋯ The study showed that gabapentin can significantly prevented opioid-induced hyperalgesia (OIH) induced caused by fentanyl and morphine, suggesting a role for the addition of gabapentin in the perioperative period and during chronic pain treatment as an effective drug to prevent OIH.

Letter Case ReportsTotal spinal block after spinal anesthesia following ongoing epidural analgesia for cesarean delivery.
There may still be an increased risk of total spinal block up to 90 minutes after the last epidural bolus.

Randomized Controlled TrialCaudal bupivacaine supplemented with morphine or clonidine, or supplemented with morphine plus clonidine in children undergoing infra-umbilical urological and genital procedures: a prospective, randomized and double-blind study.
We aimed to evaluate postoperative analgesia of morphine, or clonidine, or morphine plus clonidine, added to caudal bupivacaine in children undergoing infra-umbilical urological and genital procedures. ⋯ To conclude, we showed that 20 μg/kg of morphine added to caudal bupivacaine 0.166% plus epinephrine 1:600,000 decreased the use of analgesics in the postoperative period, although it was associated with an increased incidence of PONV. However, the addition of clonidine (1.0 μg/kg) to caudal bupivacaine provided no additional clinical benefit over bupivacaine alone.
