Randomized Controlled TrialCapsicum plaster at the Hegu point reduces postoperative analgesic requirement after orthognathic surgery.
Capsicum plaster at classical Chinese acupoints is an alternative to acupuncture, which has been used as an effective method for preventing postoperative nausea and vomiting, sore throat, and pain. In this study, we investigated the postoperative analgesic efficacy of capsicum plaster at Hegu (LI 4) acupoints in patients after bilateral sagittal split ramus osteotomy. ⋯ The capsicum plaster at the Hegu acupoints decreased the postoperative opioid requirements and opioid-related side effects in patients after orthognathic surgery.

Randomized Controlled Trial Comparative StudyManual versus target-controlled infusion remifentanil administration in spontaneously breathing patients.
The combination of propofol-remifentanil for procedural deep sedation in spontaneously breathing patients is characterized by the frequent incidence of side effects, especially respiratory depression. These side effects may be due to either the drug combination or the drug delivery technique. Target-controlled infusion (TCI) might optimize drug delivery. In this prospective, randomized, double-blind study in patients undergoing elective colonoscopy, we thus tried to answer two questions: first, if adding remifentanil to propofol surpasses the disadvantages of the combination of these two products, and second, if administration of remifentanil via TCI decreases the incidence of side effects, compared to manually controlled administration. ⋯ The combination of remifentanil and propofol for deep sedation in spontaneously breathing patients, offered better conditions for colonoscopy than propofol used as a single drug. Remifentanil administered via TCI resulted in a decrease in propofol dosing and in a lower incidence in apnea and respiratory depression (TCI n = 7, MCI n = 16, P < 0.05), compared to manually controlled administration of remifentanil.

Randomized Controlled TrialThe analgesic effect of a metered-dose 8% lidocaine pump spray in posttraumatic peripheral neuropathy: a pilot study.
A topical lidocaine patch is effective in the treatment of posttraumatic peripheral neuropathy (PTPN), but it is not suited for breakthrough pain because of difficulty with an additional application. Here, we examined the effect of 8% lidocaine pump spray (Xylocaine pump spray, XPS) on peripheral neuropathic pain caused by surgery or injury. ⋯ The present study suggests that XPS provides a significant improvement in PTPN due to its prompt analgesia, lack of systemic side effects and convenience.

Randomized Controlled Trial Comparative StudyRelative analgesic potencies of levobupivacaine and ropivacaine for caudal anesthesia in children.
Comparing relative potency of new local anesthetics, such as levobupivacaine and ropivacaine, by the minimum local analgesic concentration model has not been described for caudal anesthesia. Therefore, we performed a prospective, randomized, double-blind study to determine the minimum local analgesic concentrations of a caudal single shot of ropivacaine and levobupivacaine in children and to describe the upper dose-response curve. ⋯ In children receiving one minimum alveolar anesthetic concentration of sevoflurane, there were no significant differences in the ED(50) for caudal levobupivacaine and ropivacaine. The potency ratio at ED(50) was 0.92 and 0.89 at ED(95), indicating that caudal levobupivacaine and ropivacaine have a similar potency.

Randomized Controlled TrialPrognostic value of troponin I levels for predicting adverse cardiovascular outcomes in postmenopausal women undergoing cardiac surgery.
Adverse cardiac events that follow cardiac surgery are an important source of perioperative morbidity and mortality for women. Troponin I provides a sensitive measure of cardiac injury, but the levels after cardiac surgery may vary between sexes. Our purpose in this study was to evaluate the prognostic value of troponin I levels for predicting cardiovascular complications in postmenopausal women undergoing cardiac surgery. ⋯ In postmenopausal women, elevated troponin I levels on postoperative day 1 are predictive of MACE. Monitoring of perioperative troponin I levels might provide a means for stratifying patients at risk for adverse cardiovascular events.
