Background:Breast lumpectomy is an integral part of the treatment of mammary masses in women. This study was conducted to evaluate and compare two-drug combinations of propofol–ketamine (PK) (ketofol) and propofol–fentanyl (PF) (fenofol) on quality of sedation and analgesia in lumpectomy.Materials and Methods:This was a randomized, double-blind, clinical trial performed on 64 patients aged 15–70 years with breast cancer lumpectomy referred to Isfahan's Seyed Al-Shohada Hospital. Consequently, patients were divided into two groups of 32 patients, each group receiving PF combination or PK combination during anesthesia.Results:The patients in two groups, PF and PK, were compared in their sedation levels, severity of pain, and other variables. The mean arterial blood pressure, systolic blood pressure, and heart rate (HR) did not show any significant difference at the beginning of the study in the two groups, but the fenofol (PF) group had a significantly lower oxygen saturation than the ketofol (PK) group. The sedation level was significantly lower in the fenofol group than the ketofol group (P < 0.001). The mean pain intensity was significantly lower in the PF group than the PK group (P < 0.001).Conclusion:The two combinations of ketofol and fenofol cause rapid, favorable, safe anesthetic with minimal side effects and hemodynamic effects but it may be a superior alternative to fenofol combination, in terms of respiratory depression.
Background: Despite all of the benefits provided by laparoscopic cholecystectomy, such as rapid recovery and shorter hospital stay for patients, the incidence of postoperative nausea and vomiting (PONV) and postoperative pain (POP) still remains high. Objectives: This study was designed to compare the effects of intraperitoneal (IP) and intravenous (IV) dexamethasone on the reduction of PONV and POP. Methods: This prospective, randomized, double-blind clinical trial was conducted on a study population of 86 adult patients who were scheduled for laparoscopic cholecystectomy with the American Society of Anesthesiologists class I-II. The patients were randomized into three groups, namely IP dexamethasone (n = 29), IV dexamethasone (n = 29), and control (n = 28) groups. The patients were followed for clinical outcomes, including PONV, POP, and consumption of antiemetics, and their hemodynamic status during the first 24 hours after the surgery. Results: In the first 24 hours after the operation, no significant differences were observed in nausea (P = 0.41) and vomiting (P = 0.38) between the IP and IV dexamethasone groups. However, there was a lower severity of nausea in the IP group (P = 0.001). Additionally, the visual analog scale score representing POP was significantly reduced in the IP group (P = 0.02). No significant differences in the hemodynamic status were observed after the operation between all the three groups. Conclusions: The administration of 8 mg IP dexamethasone was associated with significantly reduced pain and severity of nausea, but not PONV, after laparoscopic cholecystectomy.
Background: A variety of anesthetics including methohexital, thiopental sodium, propofol, ketamine, and etomidate are used for electroconvulsive therapy (ECT), each accompanied by adverse effects that can cause unpleasant experiences for patients. Etomidateinduced myoclonus is among the adverse effects. We attempted to assess the effect of premedication with low-dose midazolam compared to etomidate on the reduction of this complication. Objectives: This study was designed to compare the effectiveness of low-dose etomidate and low-dose midazolam to suppress etomidate-induced myoclonus in ECT. Methods: This randomized double-blinded clinical trial was conducted on 132 patients who were candidates for ECT. They were divided into three groups of 44 patients to receive 0.015 mg/kg midazolam, 0.03 mg/kg etomidate, or placebo. Independent t-test and chi-square test were used for comparison of variables. Results: The frequency of myoclonic movements during anesthesia was different between the three groups (P value < 0.001). Myoclonic movements were significantly lower in the midazolam group than in the placebo (P value < 0.001) and etomidate (P value = 0.002) groups. In addition, the intensity of myoclonic movements was significantly higher in the midazolam group than in the placebo and etomidate groups (P value < 0.001). Conclusions: Low-dose midazolam (0.015 mg/kg) before anesthesia induction with etomidate was accompanied with significantly lower incidence and intensity of myoclonus than low-dose etomidate (0.03 mg/kg).
Objectives: The purpose of this study is a comparison of Valsalva, lidocaine, and Valsalva with administration of lidocaine to reduce the pain associated with administration of etomidate. Methods: The present study is a clinical trial study. The number of samples in each group was 30 and a total of 90 people were selected. This study was a clinical trial and the subjects were randomly divided into three groups: Group 1: Valsalva, 2: Lidocaine, 3: Valsalva and Lidocaine. Pain due to etomidate was rated on a VAS from 1 (painless) to 3 (worst imaginable pain) and their information was recorded. The collected information was entered into SPSS 22 and analyzed with appropriate statistical tests. Results: A total of 90 subjects participated in the present study and were divided into 3 groups: Valsalva, lidocaine, and Valsalva with lidocaine. No significant difference was observed between demographic variables in the study groups. There was a significant relationship between severity of pain in the three groups. According to the results, the highest pain intensity was in the Valsalva group and the lowest pain intensity was in the Valsalva with lidocaine group. Conclusions: Valsalva with lidocaine reduces the severity of pain caused by etomidate to a greater extent than other groups.
Electroconvulsive therapy is one of the methods of treatment used in various kinds of psychiatric disorders including; depression, manic disorders, and catatonia. There are also different kinds of anesthetic approaches used in electroconvulsive therapy which include different kinds of anesthetic drugs, neuromuscular blocking agents and other medications. This article reviews the recent studies conducted regarding the various methods of anesthesia used in electroconvulsive therapy and proposes drugs and methods that could decrease unwanted side-effects and improve clinical outcomes of electroconvulsive therapy.
