Noradrenergic and dopaminergic mechanisms have been proposed for the pathophysiology of seasonal affective disorder (SAD). We investigated the effects of catecholamine depletion using alpha-methyl-para-tyrosine (AMPT), an inhibitor of tyrosine hydroxylase, in patients with SAD in natural summer remission. Nine drug-free patients with SAD by DSM-IV criteria,(More)
BACKGROUND Various adjuvants are being used with local anesthetics for prolongation of intraoperative and postoperative analgesia. Dexmedetomidine, the highly selective 2 adrenergic agonist is a new neuraxial adjuvant gaining popularity. SETTINGS AND DESIGN The study was conducted in prospective, double blind manner. It included 120 American Society of(More)
BACKGROUND The aim of preemptive analgesia is to reduce central sensitization that arises from noxious inputs across the entire perioperative period. N-methyl d-aspartate receptor antagonists have the potential for attenuating central sensitization and preventing central neuroplasticity. MATERIALS AND METHODS Patients undergoing laparoscopic(More)
Literature search is a key step in performing good authentic research. It helps in formulating a research question and planning the study. The available published data are enormous; therefore, choosing the appropriate articles relevant to your study in question is an art. It can be time-consuming, tiring and can lead to disinterest or even abandonment of(More)
BACKGROUND Local anesthetic instillation in close vicinity to nerves anywhere in body blocks sensations in the same order as in central neuraxial blockade. The main purpose of this study was to evaluate the efficacy of vibration sense as criteria to determine the onset of surgical anesthesia following brachial plexus block and its correlation with loss of(More)
CONTEXT To assess the analgesic efficacy of the combination of bupivacaine and buprenorphine in alleviating postoperative pain following laparoscopic cholecystectomy. AIMS Laparoscopic cholecystectomy is comparatively advantageous as it offers less pain in the postoperative period and requires a shorter hospital stay. There are only a few studies(More)
BACKGROUND AND AIMS Various adjuncts to local anesthetics have been used with the purpose of improving the quality of subarachnoid block. This randomized double-blind study was conducted to evaluate the efficacy of adding clonidine to bupivacaine and bupivacaine-fentanyl combination. MATERIAL AND METHODS A total of 100 patients scheduled for surgery under(More)
