Quadratus Lumborum Block versus Fascia Iliaca Compartment Block for Acetabular Fracture Surgery by Stoppa Method: A Double-Blind, Randomized, Noninferiority Trial.

Background: Acetabular fracture surgeries are frequently accompanied by protracted and severe perioperative pain, and there is no consensus on optimal pain relief management.

Aim: This study aimed at comparing the analgesic efficacy of fascia iliaca compartment block (FICB) and quadratus lumborum block (QLB) in patients with acetabular fractures undergoing surgery using the Stoppa method.

Methods: In this double-blind, randomized, noninferiority clinical trial, adult patients undergoing spinal anesthesia for acetabular fracture surgery, in Imam Hossein Hospital, Tehran, Iran (IRCT20191114045435N1), were randomly divided into two groups: FICB ( = 22) and QLB ( = 24).

The Relationship between Arterial and Central Venous Blood Gases Values in Patients Undergoing Mechanical Ventilation after Cardiac Surgery.

Background: The most straightforward method of ascertaining arterial PO, PCO, and other components of blood gas is to measure them directly from a blood sample. In situations in which arterial puncture cannot be achieved or may be technically difficult, the venous blood sample can be used.

Methods: In a prospective analytical study, 80 patients undergoing mechanical ventilation after open-heart surgery in the intensive care unit were evaluated.

The Effect of Chronic Consumption of Angiotensin-Converting Enzyme Inhibitors and Angiotensin Receptor Antagonists on Blood Pressure and Inotrope Consumption After Separation from Cardiopulmonary Bypass.

Background: Chronic use of renin-angiotensin system (RAS) antagonists (angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor antagonists (ARAS)) can cause hypotension during anesthesia. In some studies hemodynamic instability, including hypotension and its effects on the clinical outcome in patients treated with these drugs during coronary artery bypass graft (CABG) and need to excessive vasoactive drugs in these patient population, has been described. The aim of this study was to evaluate the effect of chronic consumption of ACEIs and ARAS on blood pressure and inotrope consumption during coronary artery bypass graft under cardiopulmonary bypass.

The effect of low-dose remifentanil on the hemodynamic responses of endotracheal extubation.

Emergence from general anesthesia can be associated with coughing, agitation, and hemodynamic disturbances. Remifentanil may attenuate these responses. We have examined the effect of remifentanil on the hemodynamic response to the emergence from anesthesia and tracheal extubation.

High prevalence of chronic hepatitis B infection among injection drug users in Iran: the need to increase vaccination of adults at risk.

We measured the prevalence of HBV surface antigen (HBsAg) among male injection drug users (IDUs) in Detention, Tehran, Iran. A cross-sectional survey included 499 male IDUs arrested by police during a predetermined police sweep in Tehran (February, 2006). A questionnaire was filled out for each individual.

Prevalence and correlates of co-infection with human immunodeficiency virus and hepatitis C virus in male injection drug users in Iran.

Objective: Aim of the study was to evaluate the HIV and hepatitis C virus (HCV) coinfection and associated risk behaviors among Injection Drug Users in Detention, Tehran, Iran.

Methods: A cross-sectional survey included 499 male Injection Drug Users arrested by police during a predetermined police sweep in Tehran (February, 2006). At the temporary detention center, they were screened using a urine test and a physical examination for injection marks.

HIV seroconversion among injection drug users in detention, Tehran, Iran.

Jails may foster the spread of HIV, particularly among drug users. In 2006, male injection drug users (n = 499) detained in Tehran consented to HIV testing at intake and discharge. HIV prevalence at intake was 24.

Insights from a survey of sexual behavior among a group of at-risk women in Tehran, Iran, 2006.

Despite high rates of HIV among male injection drug users, the sexual behaviors of at-risk women in Iran remain unknown. A questionnaire on HIV knowledge and risk behavior was administered in a Tehran nongovernmental organization targeting runaways and other women seeking safe haven. Half (total N = 50) were less than 24 years old; baseline HIV knowledge was high.

Clinical characteristics, hospital morbidity and mortality, and up to 1-year follow-up events of acute myocardial infarction patients: the first report from Iran.

Background: Few data exist about the clinical epidemiology of acute myocardial infarction and its complications and mortality in Iran. To fill this knowledge gap, we studied clinical characteristics and the outcome for a group of Iranian patients with acute myocardial infarction, who were, for the first time in our country, followed after discharge from hospital for 1 year.

Methods: All patients (139 individuals) with confirmed acute myocardial infarction who were treated at the coronary care unit of Dr Shariati Hospital and followed up over a 1-year period (June 2002 to June 2003) were prospectively studied.
