Randomized Controlled TrialClosed-circuit anesthesia preserves skin blood flow during surgery.
Closed-circuit anesthesia (CCA) has been suggested to provide better hemodynamic stability, but the relative contribution of CCA to the control of blood flow in microcirculation is not defined. It is hypothesized that isoflurane-based CCA provides a favorable skin blood flow mediating via lesser circulatory response to surgical stimulation. This study was purposed to compare the effects of isoflurane conveyed by CCA with that by semiclosed anesthesia (SCA) on the preservation of skin blood flow in the forearm. ⋯ Closed circuit technique for isoflurane anesthesia is feasible and advantageous. It not only facilitates favorable skin blood flow but also provides better hemodynamic stability in comparison with semiclosed technique for isoflurane anesthesia.

Case ReportsCardiac arrest during spinal anesthesia: a report of two cases.
Spinal anesthesia is a widely practiced technique for both elective and emergency procedures. It is so recommended because of its efficacy and safety. ⋯ We report here two instances of cardiac arrest during spinal anesthesia in young healthy people. Discussions on the causes, management, and prevention of cardiac arrest following spinal anesthesia are also brought forward in the text.

Case ReportsCardioversion corrects cardiac arrhythmia and reverts the resultant reversed shunt flow direction during transcatheter closure of atrial septal defect--a case report.
Closure of atrial septal defect (ASD) is critically dependent on the shunt flow direction. However, shunt flow direction through ASD may change under variable clinical conditions. ⋯ The cardiac arrhythmia and altered shunt direction simultaneously reverted to the old state after cardioversion. A successful placement of Amplatzer septal occluder was successfully performed afterward and she recovered uneventfully.

Randomized Controlled Trial Comparative StudyProphylactic versus therapeutic administration of intravenous lidocaine for suppression of post-extubation cough following cataract surgery: a randomized double blind placebo controlled clinical trial.
Post-extubation cough causes considerable patient discomfort and in certain surgical procedures may lead to postoperative surgical complication. Different drugs and techniques have been used for the prevention of post-extubation cough with variable success rates. Prophylactic administration of lidocaine has been tried for the prevention of post-extubation cough with controversial results. No previous study has been performed to evaluate the therapeutic effect of intravenous lidocaine for treatment of post-extubation cough. This study was designed to compare the prophylactic effect of intravenous lidocaine with that of the therapeutic lidocaine in a sample of adult patients undergoing general anesthesia for cataract surgery. ⋯ The outcome of this study shows that prophylactic administration of lidocaine prior to tracheal extubation may be ineffective to prevent post-extubation cough. Based on the results of this study it can be recommended that post-extubation cough should be treated upon occurrence instead of routine prophylactic administration of lidocaine.

Randomized Controlled TrialBolus injection of adenosine before cardioplegic induction improves postischemic global function in coronary artery bypass grafting.
Alternative strategies to optimize preexisting cardioplegia during myocardial preservation are currently under extensive investigation. Adenosine, an endogenous purine nucleoside, has been approved for its cardioprotective potential against ischemic-reperfusion injury. Yet, little information is available with respect to the use of adenosine for cardioplegic induction in humans. The purpose of the present study was, therefore, to assess the clinical relevance of intra-aortic administration of adenosine following aortic cross-clamping with respect to the exertion of additional protection in routine coronary artery bypass surgery. ⋯ Immediate administration of 250 microg/kg adenosine via the aortic root following aortic cross-clamping could optimize the myocardial protective effect of conventional cardioplegia, quicken cardiac standstill, and offer better postoperative myocardial performance after CPB.
