[ effect of isoflurane and sevoflurane on post-op shivering]

Postoperative shivering is one of the complications that can increase the amount of oxygen consumption, so ending in a number of complications. This issue is of paramount importance in patients with an underlying cardiovascular problem. New inhalational anesthetics are increasing trends in hope to decrease a number of complications like postoperative shivering. This study was done to assess the comparative effects of sevoflurane and isoflurane on postoperative shivering. In a double blind clinical trial, the prevalence of postoperative shivering with isoflurane and sevoflurane was compared. 100 patients aged 18-65 years were selected and divided randomly into one of the two groups considering inclusion and exclusion criteria. Post anesthesia shivering was assessed and compared in the two groups. Data analysis was done using SPSS software. Student t-test and Chi-Square test were used for data analysis. A p < 0.05 was considered significant. There was no difference between the two groups regarding age, sex and the duration of anesthesia. Also, there was no statistical difference between the two groups regarding the severity and grading of shivering. Post anesthesia shivering is not so much affected using isoflurane and sevoflurane

[Effects of intravenous magnesium sulfate administration on postoperative acute pain followed by spinal anesthesia]

Magnesium is an inorganic ion. There are several products containing magnesium and it has a number of therapeutic properties. Magnesium-sulfate is a very common product and its usefulness has been proven in field of anesthesiology. This study looks at the effect of prescribing intravenous magnesium-sulfate on acute pain following orthopedic surgery of the lower extremities in patients anesthetized with spinal anesthesia method. In this double-blind, randomized, placebo-controlled clinical trial, 60 patients were selected and were randomly divided into 2 groups. Efforts were made to place both groups under the same method of anesthesia and other variable were kept constant to the best of our ability. One group received intravenous magnesium sulfate under a given protocol and the second one received the same volume of placebo, intravenously. To present the results Mean [ +/- SD] was used and the P-value of less than 0.05 was considered statisticaly significant. There was no difference between the 2 groups under basic variables. Pain reported by the first group who received magnesium sulfate was significantly less at the 1[st], 3[rd], 6[th], and 12[th] hours after the operation in comparison to the group who received placebo. At the 18[th] and 24[th] post-operation hours, there was no significant difference between the 2 groups. Receiving intravenous magnesium sulfate following lower extremities orthopedic surgery would significantly reduce the pain in the first few hours after the operation

[ effect of intra-articular magnesium sulfate on postoperative acute pain in knee arthroscopy]

Magnesium as an inorganic ion has several products containing it and has a number of therapeutic properties. A very common product, magnesium-sulfate has been proven in field of anesthesiology. This study looks at the effect of intra-articular injection of magnesium-sulfate on acute pain following knee surgery for diagnostic arthroscopy in patients undergoing general anesthesia. 60 patients were selected and divided randomly to 2 groups in this double-blind, randomized, placebo-controlled clinical trial. All anesthesia and surgery methods were the same in both groups. One group received intra-articular magnesium sulfate and the second group received the same volume of placebo. Postoperative pain scores were checked at the 1[st], 3[rd], 6[th], 12[th] and 24[th] hours after the operation by a Visual Analog Scale [VAS] pain assessment scoring system. To present the results Mean [ +/- SD] was used and the P-value less than 0.05 were considered statistically significant. There was no statistically significant difference between the 2 groups for basic variables. Pain reported by the first group who received intra-articular magnesium sulfate solution was significantly less at the 1st hour postoperatively, than the other group [8.7 +/- 1.05 vs 5.53 +/- 1.91, respectively]. Also, at the 6[th] and 12[th] hours postoperatively, the difference was significant [p<0.0001]; but it was not at the 2[nd] 18[th] and 24[th] hours, postoperatively, in comparison to the group who received placebo [p>0.3]. In patients undergoing general anesthesia for arthroscopic knee surgery, intra-articular magnesium sulfate solution significantly reduced pain in the first few hours after the surgery

[Study of prescription intravenous magnesium sulfate solution on acutepost sergical pain in spinal anestesia]

Introduction: Magnesium is an inorganic ion. There are several products containing magnesium and it has a number of therapeutic properties. Magnesium-sulfate is a very common product and its usefulness has been proven in field of anesthesiology. This study looks at the effect of prescribing intravenous magnesiumsulfate on acute pain following orthopedic surgery of the lower extremities in patients anesthetized with spinal anesthesia method

Method and Materials: In this double-blind, randomized, placebo-controlled clinical trial, 60 patients were selected and were randomly divided to 2 groups. Efforts were made to place both groups under the same method of anesthesia and other variable were kept constant to the best of our ability. One group received intravenous magnesium sulfate under a given protocol and the second group received the same volume of placebo intravenously. To present the results Mean [+/- SD] was used and the P value of less than 0.05 was accepted

Results: There was no difference between the 2 groups under basic variables. Pain reported by the first group who received magnesium sulfate was significantly less at the 1[st], 3[rd], 6[th], and 12[th] hours after the operation in comparison to the group who received placebo. At the 18[th] and 24[th] hour post operation, there was no significant difference between the 2 groups

Conclusion: Receiving intravenous magnesium sulfate following lower extremities orthopedic surgery significantly reduced pain in the first few hours after the surgery
