Effectiveness Dose of Injection Acetaminophen for Control of Shivering After General Anesthesia in Inguinal Hernia Surgery

Introduction: Inguinal hernia is the most common type of abdominal hernia which is 7 times more common in men than women. Surgical treatment is performed under general anesthesia. about 40 to 60 percent of patients of post-surgery are experiencing tremor. these patients after anesthesia, shivering is very undesirable and from the physiological aspect is very stressful, mild tremor increases the oxygen consumption like a light physical activity and judder increases the metabolic rate and oxygen consumption up to 600%. injection acetaminophen is a safe drug, in recent study determines of Effectiveness dose for control of shivering after anesthesia in surgeries. Aim: The aim of this study was to determine the effect of injection acetaminophen on the quality and timing of the Shivering after on the inguinal herniation surgery. Materials and Methods: This is a randomized double-blind study, that the statistical population was patients that were candidates for general surgery, that were referred to hospitals of Qazvin University of Medical Sciences for treatment. The patient’s undergone surgery with general anesthesia with number 1 and 2 anesthetic Class based on anesthesiologist detection. From 80 patients that were randomly selected, 40 people were selected for experimenting group with injection acetaminophen with IM injection of 0.5 mg/kg and 40 people were selected for the placebo control group (routine order). Results: The shivering in the experimenting group was decreased than the control group and was statistically significant. Tremor intensity in the experimental group was lower than the control group in all three measures [1, 2] which was also significant for comparing the linear regression, relative risk (RR) was 8in two groups according to the normal distribution of the data, in the age group between 20to 40 years the minimum range of tremor was observed and in the age group that were younger than 20 years range of tremor was observed. Conclusion: injection acetaminophen (IM) after general anesthesia can reduce the amount and severity of shivering at post-surgery and can be an effective choice drug in the post-surgery in patients with inguinal herniation surgery.
