ABSTRACT
BACKGROUND: We report on the design and implementation of a study protocol entitled Acupuncture randomised trial for post anaesthetic recovery and postoperative pain - a pilot study (ACUARP) designed to investigate the effectiveness of acupuncture therapy performed in the perioperative period on post anaesthetic recovery and postoperative pain. METHODS/DESIGN: The study is designed as a randomised controlled pilot trial with three arms and partial double blinding. We will compare (a) press needle acupuncture, (b) no treatment and (c) press plaster acupressure in a standardised anaesthetic setting. Seventy-five patients scheduled for laparoscopic surgery to the uterus or ovaries will be allocated randomly to one of the three trial arms. The total observation period will begin one day before surgery and end on the second postoperative day. Twelve press needles and press plasters are to be administered preoperatively at seven acupuncture points. The primary outcome measure will be time from extubation to 'ready for discharge' from the post anaesthesia care unit (in minutes). The 'ready for discharge' end point will be assessed using three different scores: the Aldrete score, the Post Anaesthetic Discharge Scoring System and an In-House score. Secondary outcome measures will comprise pre-, intra- and postoperative variables (which are anxiety, pain, nausea and vomiting, concomitant medication). DISCUSSION: The results of this study will provide information on whether acupuncture may improve patient post anaesthetic recovery. Comparing acupuncture with acupressure will provide insight into potential therapeutic differences between invasive and non-invasive acupuncture techniques. TRIAL REGISTRATION: NCT01816386 (First received: 28 October 2012).

Amniotic fluid embolism (AFE) is a rare, but often catastrophic, complication of pregnancy and associated with severe coagulopathy. We present an algorithm-based approach in managing coagulopathy and hemorrhage in a fatal case of histopathologically proven AFE. Thrombelastometry was used for rapid evaluation of the coagulation status. Stop of extensive hyperfibrinolysis with tranexamic acid, stabilization of initial clot formation with high-dose fibrinogen and platelet transfusions, and use of prothrombin complex concentrate together with a 1: 1 transfusion regimen of red packed cells and fresh frozen plasma was successful to control diffuse bleeding and restore clot firmness after hysterectomy. Stable clotting situation was maintained despite further clinical deterioration and development of multiple organ failure in this patient.

The release of the neuronal protein S-100B into the circulation has been suggested as an early indication of cellular brain damage. The objective of this prospective pilot study was to determine S-100B serum levels in patients undergoing cross-clamping during carotid endarterectomy (CEA) and to correlate the results with the monitoring of somatosensory evoked potentials (SSEP) and the neurological short-term outcome. Arterial blood samples of 21 patients were drawn before oral intubation, cross-clamping, and unclamping, as well as before extubation and 6 hours later. Recording of SSEP was obtained during carotid occlusion and reperfusion. If loss of SSEP appeared, cerebral ischemia was assumed and an intraluminal shunt was placed. During cross-clamping, S-100B serum levels of 14 patients increased significantly from 0.05 ng/ml to 0.21 ng/ml, but returned to baseline levels after unclamping. In 5 cases, loss of SSEP amplitudes occurred but was reversed by the shunt insertion. No significant differences of S-100B serum values, neurological examination, and carotid duplex surveillance became obvious in this group when compared to the patients with undisturbed SSEP. However, 2 patients with complete disappearance of postcentral SSEP components suffered from neurological deficits in the postoperative period. S-100B serum levels remained highly elevated 6 hours after extubation (0.78 ng/ml and 0.41 ng/ml) compared to the baseline values (0.15 ng/ml and 0.07 ng/ml). During CEA a transitory increase of the S-100B serum levels appears to present an impairment of the blood-brain barrier integrity without any neurological deficits. In contrast, persistently elevated S-100B serum levels seem to be associated with transient loss of SSEP and development of neurological deficits.
