Abstract
Background: One of the disturbing complications of propofol is pain on venous injection. Some investigators had reported that corticosteroids effectively induce and prolong the duration of local anesthetics. The aim of this study was to assess and comparing the efficacy of propofol pretreatment with dexamethasone in prevalence and severity of its pain on injection.
Materials and Methods: In a randomized, double-blinded, placebo-controlled prospective study, 90ASA I and II, 20 to 60 years-old patients scheduled for elective surgery under general anesthesia were enrolled. In all patients, one of the veins of both hands was catheterized with a 20 G catheter. Then randomly, and simultaneously 2 ml dexamethasone (8 mg) was injected to one of them and 2 ml of normal saline was injected to other. After 30 seconds, 2 ml propofol (20 mg) was injected to both hands, at the same time in 30 seconds. Pain intensity was measured using VAS system.
Results: The age mean was 32.87±5.61. Twenty nine patients were male (32.2%). The mean of pain during propofol injection was significantly lower in dexamethasone group than normal saline group (1.61 vs.4.21 respectively, p< 0.05). Also the pain incidence was significantly lower in dexamethasone group compared to normal saline group (20% vs. 57.78% respectively, p> 0.05).
Conclusion: Intravenous administration of 8 mg dexamethasone before propofol IV injection significantly decreases the pain on injection of propofol.

Abstract
Background: Tonsillectomy is the second most common pediatric surgery. Despite improvements in anesthetic and surgical technique, post-tonsillectomy pain continues to be a significant clinical concern for the patient, family, and physician. Young patients undergoing tonsillectomy experience postoperative pain and vomiting resulting in delays in oral feeding and in discharge from the hospital. Reduction of these side effects will lead to the improved quality of postoperative care. This study was performed to compare the efficacies of local Bupivacaine and intravenous Dexamethasone with that of a placebo on post-tonsillectomy pain and vomiting.
Methods: This clinical trial included 120 ASA I children, aged 3-15 years, undergoing tonsillectomy. The patients were randomly categorized into three groups: 1- local infiltration of 2 ml normal saline into the tonsillar pillar as a placebo 2- IV Dexamethasone (0.5 mg/kg, with a maximum of 16 mg) 3- local infiltration of 2 ml 0.5% Bupivacaine into the tonsillar pillar. After the operation, patients were observed regarding vomiting and pain at 0.5, 4, 24, 120 hours postextubation.
Results: Of 120 patients, 70 were male and 50 were female. The mean age of patients was 8.4 years. Three patients were missed in follow up. The questionnaire was completed for 117 patients. The mean duration of operation was longest in the placebo group (55 minutes) and shortest in Dexamethasone group (50 minutes). We noticed significant reduction in postoperative pain only in the Bupivacaine group and at the fourth postoperative hour. In the Dexamethasone group, during the first 24 hours, we could not statistically analyze the effect on vomiting. Since Bupivacaine and Dexamethasone reduce postoperative pain and vomiting, respectively, and are safe, cost-effective and available, we recommend using these drugs for tonsillectomy patients.
Conclusion: Considering the greater efficacy of Dexamethasone in the reduction of vomiting and that of Bupivacaine in pain reduction in other studies, we recommend further study to assess the use of these two drugs together.

Abstract
Background: In rhinoplasty, periorbital edema and ecchymosis is due to soft tissue trauma and small vessel injury with subsequent exudation and bleeding. The main purpose of this study is to determine the effect of dexamethasone in reducing periorbital edema and ecchymosis and intraoperative bleeding in rhinoplasty patients.
Methods: This double-blind study included 90 patients who underwent rhinoplasty from October 2004 to March 2005. In group A, 8 mg of intravenous dexamethasone was administered only preoperatively. In group B, 8 mg of dexamethasone was administered preoperatively and continued every 8 hours postoperatively. Group C, the control group, received no dexamethasone.
Results: The degree of upper lid edema in groups A and B was significantly less than that of group C. During the first and second day the severity of upper lid edema in group B was less than that of group A, but the difference was not significant. The degree of lower lid edema during the first and second days in groups A and B was significantly less than that of group C, although it was identical in all groups during the fifth and seventh days. The degree of upper lid ecchymosis during the first and fifth days in group C was significantly more than that of groups A and B, but it was similar on the seventh day in all groups. The degree of lower lid ecchymosis on the first day in groups A and B was significantly less than that of group C however, it was similar in all groups during the second, fifth and seventh days. The volume of intraoperative bleeding in the three groups was similar. The mean period of recovery (12 days) was comparable in all groups.
Conclusions: Dexamethasone administration leads to the reduction of upper lid edema, ecchymosis and lower lid edema during the first and second postoperative days, and reduction of lower lid ecchymosis on the first postoperative day.

Abstract
Background: The decision to extubate the patient is crucial and challenging. The use of corticosteroids to reduce airway edema and extubation failure in intensive care patients is debatable.
Methods: In an observational prospective cohort study from April 2021 to July 2021, 110 patients undergoing head and neck surgery at Imam Khomeini Hospital's special wards were enrolled. Inclusion criteria: Patients undergoing head and neck surgery. Exclusion criteria: previous corticosteroid use, presence of tracheostomy tube, history of head and neck surgery. The intervention group (n=55) received intravenous dexamethasone 8 mg three times a day for the first 24 hours and 4 mg twice a day for the next 24 hours. The control group did not receive any corticosteroids (n=55). All the patients were weaned with the same protocol, including pressure support ventilation with pressure support 6-8 cm H20 and PEEP <5 cm H2o and FIO2 ≤0.4 for 1-2 hours without respiratory distress, hypoxia, tachycardia, and diaphoresis. Before extubation, the cuff leak test was done for all the patients with the cut-off point of 110 ml. The Chi-square or Fisher's exact test was performed for categorical variables, and a t-test was used to describe the quantitative variables. P-values less than 0.05 were considered statistically significant.

Results: The mean age was 52.1±14.1, and there was no difference between the two groups. Demographic characteristics, including sex, body mass index, duration of surgery, kind of intubation, and Acute Physiology and Chronic Health Evaluation (APACHE) II score, were not significantly different. The length of stay in the intensive care unit in the dexamethasone group was significantly longer than the control group (104 vs. 79-hour, P=0.001, CI 95%: 10.995-40.878). The rate of failure in extubation and postoperative stridor was not significantly different between the two groups (P=0.237).
Conclusion: Dexamethasone usage seems not to be effective in reducing airway edema, and its routine use is not recommended in reducing stridor after endotracheal tube removal.

Abstract
Background: In this study, the effect of intravenous dexamethasone on pain, nausea and vomiting after laparoscopic ovarian surgery was investigated.
Methods: This randomized clinical trial was conducted from June 2019 to March 2019 on patients undergoing laparoscopic ovarian cystectomy in Beheshti Hospital, Isfahan. In this study, 88 patients aged 18 to 45 years were included in the study. Patients were randomly divided into two groups receiving dexamethasone (D) and normal saline (S). Two minutes before induction of anesthesia, the first group received 8 mg (2 ml) of dexamethasone and the second group received normal saline (2 ml). The duration of surgery and stay in recovery, the frequency of pain and nausea and vomiting, the need for analgesic and anti-nausea drugs, and the cardiovascular response during the study were evaluated and recorded.
|
Results: No significant difference was seen in terms of demographic characteristics between the two groups (P>0.05). The frequency of pain during recovery (P=0.4) was not significantly different between the two groups, but at 2 hours (P=0.005), 12 hours (P<0.001) and 24 hours after the operation (P=0.005) (P=0) was significantly lower than S group. The frequency of nausea in group D during recovery (P=0.003), 2 hours later (P<0.001), and 12 hours (P=0.002) was significantly lower than group S, but 24 hours after the surgery, there was no significant difference between the two groups (P=0.15). During recovery, there was no vomiting in both groups (P=1), the frequency of vomiting in 2 hours (P=0.003), 12 hours (P<0.002) and 24 hours after the operation (P=0.48) in group D was lower than S. At the time of the study, the dose of diclofenac and metoclopramide received in group D patients was lower than group S. There was no significant difference in cardiovascular response between the two groups during the study (P>0.05).
Conclusion: Dexamethasone with a dose of 8 mg before induction of anesthesia can be effective in reducing pain, nausea and vomiting after laparoscopic ovarian surgery and reducing the need for analgesics and anti-nausea drugs.

Abstract
Background: Postoperative nausea and vomiting (PONV) is a common challenge in cesarean surgeries, on the other hand, the use of dexamethasone has been proposed as an effective prophylaxis in the management of these complications. This study evaluated the effect of dexamethasone in reducing PONV.
Methods: This study was conducted as a randomized and double-blind clinical trial from April 2022 to September 2023 at Razi Hospital of Jundishapur University of Medical Sciences, Ahvaz. Elective cesarean section patients under spinal anesthesia were divided into two groups of 30 people. In this research, there were two groups: a group that received 0.1 mg/kg dexamethasone (Iran company) and a placebo group that received normal saline. The injections were done before the start of anesthesia, and both groups had received 500 cc of normal saline serum before drug injection. During the surgery and after that at specific time intervals, parameters such as blood pressure, heart rate, and the occurrence of nausea and vomiting were recorded through the V&N scoring table and shivering through the shivering scoring table. Recorded 1/2/4/6/12 after surgery.
|
Results: In this study the investigated variable is postoperative nausea and vomiting (PONV), since the investigated variable is a qualitative/nominal variable, to calculate the sample size from the formula P1- P2 ∕√P(1-P) used. The significance level of the tests is considered to be less than 0.05 and data analysis was done with SPSS type 23 software. Although no significant difference was observed between dexamethasone and placebo in the first hour after the operation, in the following hours, dexamethasone significantly reduced nausea and vomiting, on the other hand, heart rate and blood pressure decreased faster in the groups receiving dexamethasone.
Conclusion: Dexamethasone is significantly effective in reducing nausea and vomiting after cesarean surgery. It also has a positive role in reducing the heart rate and blood pressure and This drug is particularly effective in controlling complications after spinal anesthesia after the operation.
