Regional techniques and outcome: what is the evidence?

Abstract: Perioperative use of regional analgesic techniques may provide improvement in conventional outcomes, although the benefit appears to be limited to high-risk patients and those undergoing high-risk procedures. The benefits conferred by perioperative regional anesthetic techniques need to be weighed against any potential risks and this should be assessed on an individual basis.

“…Their use may benefit the elderly more than younger patients, due to the relatively greater risk of side-effects in the older adult if opioids were otherwise used [13,[66][67][68], although, as ever, more research is required comparing postoperative opioid with regional analgesia in the elderly. Age-related alterations in both anatomy and neural micro-anatomy may make correct siting of any block technically more difficult, and drug effects less predictable [69], blockade being achieved with lower doses of local anaesthetic [70] and lasting longer [71].…”

“…ASA status, as stated in the literature, correlates with perioperative mortality "even better than other classifi cations of mortality and morbidity" 7,8 . TEA is considered to exert some protective eff ect against POAF 9 . Arterial hypertension was not confi rmed as a risk factor for POAF, in contrast to the 2014 American Heart Association Atrial Fibrillation Guidelines and relevant literature 1,2,4 .…”

“…The number of patients was based on the literature 12 . To detect a difference of approximately 30% between groups, assuming an alpha error of 0.5% and a beta error of 20%, we estimated at 20 the required the number of patients in each group totaling 40 patients.…”
