Orbital regional anesthesia.

Abstract

Orbital regional anesthesia is a useful and safe modality for providing excellent operating conditions for the surgeon and painless, pleasant circumstances for the patient. It is especially suited for patients who are extremely sensitive and who could not tolerate topical anesthesia or a sub-Tenon's block without deep sedation. Both intraconal and extraconal techniques can be used safely and effectively if proper precautions are taken to enter the safest areas of the orbit and to avoid the vascular areas and the deep orbit where structures are tightly packed and thus more easily harmed. Thorough knowledge of orbital anatomy and understanding of the globe-orbit relationship of every patient are necessary to perform this form of regional anesthesia. In addition, knowledge of the effects and side effects of the anesthetics and adjuvants is also required.

Regional versus general anaesthesia for caesarean section.

BACKGROUND: Regional and general anaesthesia (GA) are commonly used for caesarean section (CS) and both have advantages and disadvantages. It is important to clarify what type of anaesthesia is more efficacious. OBJECTIVES: To compare the effects of regional anaesthesia (RA) with those of GA on the outcomes of CS. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 December 2005), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2005, Issue 1), MEDLINE (1966 to December 2005), and EMBASE (1980 to December 2005). SELECTION CRITERIA: Randomised and quasi-randomised controlled trials evaluating the use of RA and GA in women who had CS for any indication. DATA COLLECTION AND ANALYSIS: Two authors independently assessed trials for inclusion, data extraction and trial quality. MAIN RESULTS: Sixteen studies (1586 women) were included in this review. Women who had either epidural anaesthesia or spinal anaesthesia were found to have a significantly lower difference between pre and postoperative haematocrit (weighted mean difference (WMD) 1.70, 95% confidence interval (CI) 0.47 to 2.93, one trial, 231 women) and (WMD 3.10, 95% CI 1.73 to 4.47, one trial, 209 women). Compared to GA, women having either an epidural anaesthesia or spinal had a lower estimated maternal blood loss (WMD -126.98 millilitres, 95% CI -225.06 to -28.90, two trials, 256 women) and (WMD -84.79 millilitres, 95% CI -126.96 to -42.63, two trials, 279 women). More women preferred to have GA for subsequent procedures when compared with epidural (odds ratio (OR) 0.56, 95% CI 0.32 to 0.96, one trial, 223 women) or spinal (OR 0.44, 95% CI 0.24 to 0.81, 221 women). The incidence of nausea was also less for this group of women compared with epidural (OR 3.17, 95% CI 1.64 to 6.14, three trials, 286 women) or spinal (OR 23.22, 95% CI 8.69 to 62.03, 209 women). No significant difference was seen in terms of neonatal Apgar scores of six or less and of four or less at one and five minutes and need for neonatal resuscitation with oxygen. AUTHORS' CONCLUSIONS: There is no evidence from this review to show that RA is superior to GA in terms of major maternal or neonatal outcomes. Further research to evaluate neonatal morbidity and maternal outcomes, such as satisfaction with technique, will be useful.

[Perineal regional anaesthesia: indications in gynaecologic and proctologic surgery and in obstetric].

Perineal and proctologic surgery is well known as very painful. The apparition of new specific needles, long acting and less toxic local anaesthetics and neurostimulation allowed reconsidering some old forgotten techniques. Those blocks appear really useful to optimize multimodal postoperative analgesia and postoperative rehabilitation. After anatomic review, authors describe perineal regional anaesthesia and discuss about main indications and advantages, in the eyes of their experience and bibliographic review.
