Abstract

Background and Objective: Using of laryngeal mask air way (LMA) was recommended for air way management in short duration elective surgeries. One of its side effects is the increasing of secretion of air way and subsequently laryngospasm. Anticholinergic drugs (hyoscine NBB and atropine) have been administrated to reduce of these side effects. This study was carried out to compare the atropin and hyoscine n-butylbromide (NBB) on hemodynamic and nausea and vomiting in anesthesia with laryngeal mask air way. Materials and Methods: In this randomized double- blind control trials, 100 patients (20-50 years) with class 1 and class 2 of Anesthesia, have been operated less than one hour under general anesthesia with LMA during 2007-08 in Beheshti hospital. These patients were divided to 2 groups every other one randomly with equal persons. After controlling the base of heart rate (HR) and mean arterial pressure (MAP), both groups was administrated to premed according weight. Then 0.5mg/5ml atropine to the first group and 10mg/5ml hyoscine NBB (Buscopan) to the second group was injected and hemodynamic was controlled after two minutes. Anesthesia with thiopental sodium was induced and LMA was inserted. Then hemodynamic was controlled during the time. The amount of secretions of air way was investigated according to the numbers of suction at the end of surgery and after removing of LMA. The severity of postoperative nausea and vomiting was assessed with attention to need of patients to antiemetic until 6 hours. Data was analyzed statistically. Results: Antiemetic effect of atropin and hyoscine n-butylbromide (NBB) was similar. With mild secretions, moderate and sever antisialague effect of hyoscine NBB was 80%, 18% and 2% and in atropine group was 72%, 22% and 6% retrospectively. Heart rate increase (less of 20%) without rising MAP was obsered in two groups. Conclusion: This study showed that the effects of hyoscine and atropine in decreasing airway secretions, nausea and vomiting is similar.

Abstract

Background and Objective: Cardiac arrest is responsible for half of the death cases, which is preventable in rapid and effective cardiopulmonary resuscitation (CPR). During the last years, a great amount of progress has occurred in this field, but there is still a lack of enough data for CPR. The aim of this study was to assess and compare the survival rate of patients undergoing CPR in two university hospitals in Tehran, Iran. Materials and Methods: In this retrospective analytical study, the survival rate of 178 patients undergoing CPR in the emergency department of two university hospitals (Taleghani and Shaheed Modarres) were assessed and compared during 2005. The related variables including the time delay for CPR, the time length for CPR and the outcome of CPR were analyzed. Results: 24 hours after the cardiac arrest, 7 cases of 54 (13%) survived in Taleghani hospital and 33 of 124 (26.6%) survived in Shaheed Modarres hospital (P<0.05). Conclusion: This study showed that the rate of short term survival of patients after CPR is similar to other parts of country but lower than the other parts of the world.

Abstract

Background and Objective: Previous studies suggest a correlation of central venous pressure (CVP) and peripheral venous pressure (PVP) in different surgeries. CVP is one of essential monitoring during coronary arterial bypass graft (CABG). Canulation of peripheral venous catheter and PVP measurement is easier, whit less complication. This study was done to compare the central venous and peripheral venous pressures in the antecubital region in coronary arterial bypass graft surgery. Materials and Methods: This descriptive analytical study was done on 84 patients with American society of anesthesiology III with CABG surgery in Shafa hospital, Kerman, Iran during 2007. The technique of anesthesia was the same in all patients. CVP and PVP were measured every 20 minutes intervals before, on and after cardio-pulmonary pump. Data were analyzed using STAT-10, ANOVA and linear regression tests. Results: A total of 750 simultaneous measurements of CVP and PVP were recorded in all patients. The mean of CVP before of pump was 6.8±0.9 and the mean of PVP was 8.8±1. The mean difference between CVP and PVP was ±2 mmHg and this difference was significant (P<0.05). The mean of CVP on pump was 3.9±1 and the mean on PVP was 7.6±1. The mean difference of these two changeable was ±3.7 mmHg. This difference was significant (P<0.05). The mean of CVP after of pump was 6.5±1 and the mean of PVP was 8.5±1. The mean difference this two changeable was ±2 mmHg and this difference was significant (P<0.05). Conclusion: PVP and CVP are related with each other on cardio-pulmonary pump even in severe hemodynamic condition. PVP and CVP changes are synchronized and PVP is a helpful clinical alternative for estimation of CVP.

Abstract

Background and Objective: Post-operative nausea vomiting (PONV) and laryngospasm are the most common of complication following surgery. This study was conducted to compare the incidence of laryngospasm and PONV after pediatric infra umbilical surgery using two anesthetic methods: control ventilation and spontaneous respiration. Materials and Methods: This double-blind clinical trial study was conducted on 192 children with 2-7 year-old undergoing infra-umbilical surgery of ASA-I class with the estimated operation period of an hour in Tehran pediatric hospital, Tehran-Iran during 2009-10. The patients were randomly divided into two groups: controlled ventilation and spontaneous respiration. After anesthetization, Atracurium was injected to the control ventilation (CV) group and anesthesia continued with mechanical ventilation. For the patients of the second group (spontaneous respiration/SR), after the gradual increase of the dose of halothane and certainty of the optimal depth of anesthesia, patients were intubated to allow spontaneous respiration. After intubation, all patients were anesthetized with Halothane 1-2% and the N2O/O2. The rate of nausea, vomiting, laryngospasm, excessive post-operative discharge was recorded. Data were analyzed using SPSS-13, student’s t-test, chi-square and Fisher’s exact tests. Results: Post-operative nausea was non significantly higher in CV group (8%) than SR (6.52%). The rate of vomiting was higher in CV (16%) as compared to SR group (2.17%). (P<0.001, RR=8.57, CI: 1.91-38.41). The rate of laryngospasm at the end of the surgery was higher in CV group (15.21%) as compared to SR group (26%) (P<0.02, RR= 0.94, CI: 0.05-1.77). The rate of excessive discharge at the end of the surgery was significantly higher in CV group (52%) in comparison with SR group (11.95%) (P<0.001, RR=0.94, CI: 0.05-1.77). Conclusion: This study showed that in infra-umbilical surgeries in a period of less than an hour the incidence of post-operative vomiting and laryngospasm is higher in control ventilation group than spontaneous respiration group, which might be due to the injection of neostigmine to counter-act the effects of muscle relaxants.

Abstract

Background and Objective: Electro convulsion therapy (ECT) is one of the most common ways for treatment of psychiatric disorders. The aim of this study was to compare the effect of Propofol, Etomidate, and Thiopental on seizure and recovery duration following ECT.
Methods: In this clinical trial study, 90 patients diagnosed with a psychiatric disorder by a psychiatrist, who need to be treated by ECT in 5 Azar hospital, Gorgan, north Iran. The patients were randomly divided into the three groups by simple random allocation method. Interventions included standard monitoring and pre-oxygenation with 100% FiO2 for 3 minutes for all patients in three groups. Anesthesia of the patients in the first, second, and third group was done with Thiopental (1.5 mg/kg), Propofol (0.6 mg/kg), and Etomidate (0.1 mg/kg), respectively. Administration of Succinyl Colin (0.5 mg/kg) as muscle relaxant and Atropine for prevention of bradycardia was uesd in all patients. Duration of seizure and recovery; changes in hemodynamic status including heart rate (HR) and mean arterial pressure (MAP); and amount of charge for ECT were recorded for each subject.
Results: Mean of seizure duration in Thiopental, Propofol, and Etomidate groups were 43.72±11.81, 35.74±10.58 and 45.81±17.26 seconds, respectively (P<0.05). Amount of charge for ECT in 3 sessions of treatment and changes of HR were not different between the 3 groups. Changes of MAP in the Propofol group was significantly less than other two groups (P<0.05). Recovery time following ECT was the least in Etomidate group in comparison with Thiopental and Propofol (P<0.05).
Conclusion: Ethomidate and Thiopental had the same effect on increasing seizure duration. However, due to the significant reduction in recovery time compared with Thiopental, Ethomidate may be considered as the best choice.

Abstract

Background and Objective: Ventilator-associated pneumonia (VAP) is an important complication in intensive care unit (ICU) patients with endotracheal intubation. Finding potential early indicators of this condition can aid in reducing the disease burden. We aimed to investigate the relationship between VAP occurrence and serum levels of C-reactive protein (CRP), procalcitonin (PCT), and hemoglobin (Hgb) during ICU hospitalization of brain trauma patients.
Method: This descriptive-analytical study was carried out on brain trauma patients (99 male, 39 female), referring to the 5th Azar hospital in Gorgan, Iran, in the course of 2017. The patients were hospitalized in ICU with endotracheal intubation and mechanical ventilation. The diagnosis of VAP was confirmed by a 12-score rating based on chest radiographs, body temperature, white blood cell count, and sputum culture. After admission, serum CRP, PCT, and Hgb were documented daily for 6 days.
Results: According to the diagnostic criteria, VAP was confirmed in 41 patients (30%). Serum CRP and PCT levels on the 6th-day post-admission were significantly associated with VAP diagnosis, while Hgb levels did not differ significantly between VAP and non-VAP patients. Serum levels of CRP, PCT, and Hgb on the 6th day were not associated with age or sex.
Conclusion: Our results indicate that serum CRP and PCT levels are associated with the occurrence of VAP in ICU patients receiving mechanical ventilation. Therefore, these biomarkers could be utilized to warn physicians about the possibility of VAP, thereby reducing mortality rate and hospitalization length.

Abstract

Background and Objective: Lidocaine is the most effective anesthetic and a valuable drug for nerve pain control and management. Dexamethasone is commonly used to prevent postoperative nausea and vomiting. Dexamethasone, together with a local anesthetic, enhances the peripheral nerve block. Therefore, this study was conducted to compare the duration of anesthesia and analgesia effects after surgery in 2 anesthesia methods.
Methods: This descriptive-analytical study was conducted on 50 patients aged 18 to 70 years who were candidates for orthopedic surgery and visited the 5th Azar Medical Training Center, Gorgan, Iran during 2021. The sample was selected via convenience sampling and by checking the inclusion criteria. In group 1, 10 ml of Lidocaine 1%, and in group 2, 8 ml of 1% Lidocaine and 2 ml of dexamethasone were used as infiltration in the operation site. The average onset of analgesia and the duration of analgesia as well as postoperative pain between both anesthesia methods were determined and compared with the visual analog scale.
Results: The average duration of anesthetic effect was significantly higher in group 2 (P<0.05). In addition, the average pain duration of the patients of group 2 had a downward trend from the time of entry to when they exited the recovery room (P<0.05).
Conclusion: The combination of dexamethasone and Lidocaine increased the duration of finger nerve block effect and analgesia after surgery.
