Granisteron Versus Ondansetron for Prophylaxis Against Post-Spinal Anesthesia Shivering: a Randomized Controlled Study
3. Scientific committee approval (Was it scientifically approved by the department?) Yes
Date of approval: Sunday ,1ST September,2019
Background and Rationale:
Regional anesthesia is commonly associated with intraoperative shivering which reaches 40-60%. Spinal anesthesia contributes in impairment of thermoregulation, and predisposes patients to hypothermia, which reduces the threshold for shivering and vasoconstriction. Other mechanisms responsible for shivering include increased sympathetic tone, pain, and systemic release of pyrogens. Shivering causes increase in metabolic activity, oxygen consumption, intracranial, and intraocular pressure. Shivering is also responsible for increasing cardiac output, peripheral resistance, carbon dioxide production, and lactic acidosis. Furthermore, shivering interferes with electrocardiogram (ECG) and pulse oximetry. 1 Post anaesthetic shivering is one of the most frequent problems in the early recovery phase following general anaesthesia. It was considered as the sixth most important problem of current clinical anaesthesiology among 33 low morbidity clinical outcomes. Previous studies have found that shivering occurs up to 60% of patients in the postoperative period and varies according to sex, age, drugs used for anaesthesia and the duration for the surgery.2 Since shivering is a response to hypothermia, body temperature should be maintained within 36.5-37.5°C, however, shivering may be also seen in normothermic patients undergoing regional anesthesia. A number of factors responsible for developing of hypothermia in regional anesthesia including age, level of sensory block, temperature of the operating room and infusion solution.3 Perioperative hypothermia and shivering can be prevented by physical methods like surface warming or pharmacologically by drugs such as pethidine, tramadol, clonidine, doxapram, opioids, neostigmine, magnesium sulfate and ketamine.4 Pethidine is the most commonly used drug for post spinal anesthesia shivering. The disadvantage of pethidine is that it can cause respiratory depression in the presence of previously administered opioids or anaesthetics. Moreover, hypotension, nausea and vomiting are also important side effect of pethidine.5 Pethidine, which is considered as a time-tested drug for control of shivering, can have adverse effects such as respiratory depression, nausea, and vomiting. which begs to investigate the efficacy of other drugs.6 5-HT antagonists had been effectively introduced for management of perioperative shivering by inhibiting thermoregulatory response by central mechanism. Ondansetron is a 5-HT antagonist which had been effectively used in treatment of postoperative shivering.7 Granisteron, a new generation of 5-HT antagonists, had been also reported effective in the prevention of Postoperative shivering.9-10 No data are available about the comparison of both drugs, ondansetron and granisteron, for prophylaxis against post-spinal shivering The aim of the investigator's study is to compare the efficacy of granisteron to ondansetron for prevention of intra- and post spinal anaesthesia shivering.
