Bilateral pudendal nerves block for postoperative analgesia with 0.25% S75:R25 bupivacaine. Pilot study on outpatient hemorrhoidectomy.
Hemorrhoidectomy may be performed under several anesthetic techniques and in outpatient regimen. Postoperative pain is severe and may delay discharge. This study aimed at evaluating bilateral pundendal nerves block for post- hemorrhoidectomy analgesia. ⋯ Bilateral pudendal nerves block oriented by nerve stimulator provides excellent analgesia with low need for opioids, without local or systemic complications and without urinary retention. Controlled studies might be able to show whether this should be the first analgesic option for hemorrhoidectomies. Perineal anesthesia lasting 20.21 hours shall induce further studies with stimulator-oriented pudendal block.

Postoperative pain, nausea and vomiting in neurosurgical patients.
Postoperative pain and postoperative nausea and vomiting are significant problems for neurosurgical patients and their carers. The treatment of these problems is widely perceived to be inadequate, however, especially in patients undergoing craniotomy, and there are few large, randomized controlled trials. The main issue has been fear of side effects, especially those masking neurological signs. A review of the recent literature therefore is justified. ⋯ There is still a lot of scope to research and refine pain and postoperative nausea and vomiting management in cranial and spinal neurosurgical patients. Large-scale studies are required to define the current state of practice, determine effective treatments and define the incidence of side-effects.

Myocardial protection defines the set of strategies aiming at attenuating the intensity of myocardial ischemia-reperfusion injury during heart surgery and its harmful consequences on myocardial function. A better understanding of pathophysiological phenomena related to ischemia-reperfusion events and of the anesthetic-induced heart protection has given to the anesthesiologist a major role in intraoperative myocardial protection. The objective of this update was to review the mechanisms of ischemia-reperfusion-induced myocardial injury and myocardial protection modalities focusing on anesthetic techniques. ⋯ The association of adequate anesthetic technique using heart protecting agents to usual myocardial protection modalities performed by the surgeon may contribute to the prevention of cardiac surgery-induced myocardial dysfunction and improve postoperative outcome.

This review was performed through a Medline research to evaluate articles published between January 2004 and April 2005. Technical procedures, indications, drugs, infusion regimens, and complications of continuous peripheral nerve blocks were considered. ⋯ Continuous peripheral nerve blockade is an effective and safe technique for postoperative analgesia, even when administered at home. To optimize this technique, further studies are needed to help minimize the risk of side effects, improve techniques to locate the targeted nerve (stimulating catheters or ultrasound imaging) and choose less toxic drugs (levobupivacaine and ropivacaine) with more effective infusion regimens.

[Postoperative nausea and vomiting: a review of the 'minor-major' problem.].
Notwithstanding continuous investigations and the development of new drugs and techniques, postoperative nausea and vomiting (PONV) are frequent and may contribute to the development of complications, thus increasing hospital and human costs. This article aimed at reviewing physiological mechanisms, risk factors and therapeutic approaches available to manage PONV. ⋯ Although the management of PONV has improved in recent years, it is still common among high-risk patients. Current strategy to prevent and treat PONV is not yet established and Gan guidelines should be adapted to each population and institution.
