OBJECTIVE: Adjustment in the doses of opioids has been a focus of interest for achieving better fast-track conditions in cardiac anesthesia, but relatively sparse information exists on the potential effect of psychologic and behavioral factors, such as stress, anxiety, and type of personality, on anesthesia requirements and patient turnover in the cardiac recovery unit (CRU); to the authors' knowledge, this particular focus has not been systematically investigated. In this randomized study, the authors tested the hypothesis that low-dose sufentanil, compared with a standard dose, can improve fast-track parameters and the overall quality of recovery...

BACKGROUND AND OBJECTIVES: Pain is an aggravating factor of postoperative morbidity and mortality. The aim of this study was to compare the effects of methadone versus morphine using the numerical rating scale of pain and postoperative on-demand analgesia in patients undergoing myocardial revascularization. METHOD: A randomized, double-blind, parallel clinical trial was performed with patients undergoing coronary artery bypass grafting. The subjects were randomly divided into two groups: Morphine Group (MoG) and Methadone Group (MeG)...

BACKGROUND: A cardioprotective role of morphine acting via opioid receptors has been demonstrated, and previous preclinical studies have reported that morphine could reduce reperfusion injury and myocardial infarct size in a way similar to that of ischemic periconditioning. This study aimed to evaluate the effect of intracoronary morphine on myocardial infarct size in patients with ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention. METHODS AND RESULTS: This study was designed as a 2-center, prospective, randomized, open-label, blinded end point trial...

We describe the case of a 23-year-old white female, 10-12 weeks pregnant, with a history of intravenous drug use and a recently diagnosed pneumonia, who was found deceased in her bed after a night of sleep. Although postmortem serum toxicology tested positive for alprazolam, tetrahydrocannabinol, and morphine, the ultimate cause of death was determined to be cardiac tamponade secondary to an isolated abscess in the ascending aorta. The patient had several risk factors for aortic rupture and cardiac tamponade including intravenous drug use, pneumonia, and pregnancy...

INTRODUCTION: QT dispersion is the difference between the maximum and minimum QTc interval in a 12-lead electrocardiogram (ECG). Some researchers have demonstrated the effects of an increase of QT-d in STEMI and its reduction with successful therapy. The aim of this study was to investigate the morphine post-conditioning effect on the QT dispersion in patients undergoing primary percutaneous coronary intervention (PCI) on anterior descending cardiac artery. METHODS: This cohort study was conducted on STEMI patients admitted to the Hospital of Imam Reza (AS), Mashhad, Iran, from March 2015 to February 2016 who were undergoing primary angioplasty on the anterior descending cardiac artery...

STUDY OF OBJECTIVE: To compare the effects of oral tramadol+paracetamol combination on morphine consumption following coronary artery bypass grafting (CABG) in the patient-controlled analgesia (PCA) protocol. DESIGN: A prospective, double-blind, randomized, clinical study. SETTING: Single-institution, tertiary hospital. PATIENTS: Fifty cardiac surgical patients undergoing primary CABG surgery. INTERVENTIONS: After surgery, the patients were allocated to 1 of 2 groups...

STUDY OBJECTIVE: Postoperative cognitive dysfunction (POCD) is a well-known complication after cardiac surgery and may cause permanent disabilities with severe consequences for quality of life. The objectives of this study were, first, to estimate the frequency of POCD after on-pump cardiac surgery in patients randomized to remifentanil- or sufentanil-based anesthesia and, second, to evaluate the association between POCD and quality of recovery and perioperative hemodynamics, respectively...

Background Single-session hypnosis has never been evaluated as a premedication technique in patients undergoing coronary artery bypass grafting (CABG). The aim of the present study was to evaluate the beneficial effects of clinical hypnotherapy on perioperative anxiety, pain perception, sedation, and necessity for ventilator assistance in patients undergoing CABG. Methods Double-blind, randomized, clinical trial was performed. Forty-four patients undergoing CABG surgery were randomized into two groups. The patients in group A received preprocedural hypnosis by an anesthesiologist...

OBJECTIVE: Progressive cost containment has resulted in a growing interest for fast-track cardiac surgery. Ventilation time and length of stay (LOS) in the intensive care unit (ICU) are important factors in patient turnover, a more efficient use of resources, and early patient mobilization. However, LOS in ICU is not an objective measure because, in addition to medical factors, patient discharge may be guided by logistics and policy, and thus more objective measures are warranted. The authors hypothesized that remifentanil compared with sufentanil would reduce ventilation time and LOS in the ICU and that remifentanil would have beneficial effects on the overall quality of recovery...

OBJECTIVE: The aim of this study was to compare narcotic use in the perioperative hospital stay as a measure of pain in patients undergoing robotic versus conventional coronary artery bypass grafting (CABG). METHODS: Propensity score matching of patients undergoing robotically assisted CABG and conventional CABG over a period of 5 years was performed. A retrospective chart review was performed to identify the total amount of narcotics used by both groups calculated as morphine equivalent dosing (MED)...

We investigated the effect of high spinal anesthesia on postoperative delirium in opium dependent patients undergoing coronary artery bypass grafting (CABG). The study was conducted in a tertiary referral university hospital on a population of 60 opium dependent patients undergoing CABG surgery. Patients were divided into two groups based on anesthesia protocol. One group were given general anesthesia (GA Group), the other group additionally received intrathecal morphine and bupivacaine (SGA Group). Postoperative delirium (POD) was defined as the main outcome of interest...

The aim of this study was to investigate the protective mechanisms of delayed-phase morphine preconditioning on myocardial ischemia-reperfusion injury. Thirty healthy male New Zealand white rabbits were randomly divided into three groups: a sham operation group (C), ischemia-reperfusion group (I/R), and delayed-phase morphine preconditioning group (M) (N = 10/group). Rabbits in the C group received thoracotomy for 160 min. Rabbits in the I/R group received left artery blockage for 40 min and reperfusion for 120 min...

Numerous interventions have been shown to limit myocardial infarct size in animal models; however, most of these interventions have failed to have a significant effect in clinical trials. One potential explanation for the lack of efficacy in the clinical setting is that in bench models, a single intervention is studied without the background of other interventions or modalities. This is in contrast to the clinical setting in which new medications are added to the "standard of care" treatment that by now includes a growing number of medications...

This study aimed to investigate the protective effects of delayed morphine preconditioning on myocardial ischemia-reperfusion injury. We randomly divided 30 rabbits into three groups with 10 rab-bits in each group as follows: sham operation group (C group), isch-emia-reperfusion group (I/R group), and morphine pretreatment group (M group). Rabbits in C Group received left coronary without blocking for 160 min. The left descending artery of rabbits in the I/R group was blocked for 40 min and reperfused for 120 min...

BACKGROUND: Plasminogen activator inhibitor-1 (PAI-1) is a glycoprotein with inhibitory effects on the formation of plasmin from plasminogen by plasminogen activator. Thus, it prevents clot lysis in vessel walls. Several evidences prove the relationship between coronary artery disease and response to fibrinolytic therapy in patients with myocardial infarction (MI) with PAI-1 level. Opium addiction is one of the most important factors in causing MI and cardiovascular events. This is due to it causing imbalance between coagulation and anticoagulation factors in the blood...

BACKGROUND: Opioids can mimic the effects of remote cardiac preconditioning and mediate a subsequent reduction in myocardial infarct size. AIM: This study investigated the role of beta-endorphin (β-EP) in intracerebroventricular morphine cardioprotection. METHODS: Anesthetized, open-chest, male Sprague-Dawley rats were assigned to 1 of 9 treatment groups 3 days after intracerebroventricular catheter placement. Remote preconditioning was induced with 3 μg/kg of morphine...

BACKGROUND: Our study aimed to compare HTEA and intravenous patient-controlled analgesia (PCA) in patients undergoing coronary bypass graft surgery (CABG), based on haemodynamic parameters and myocardial functions. MATERIALS AND METHODS: The study included 34 patients that were scheduled for elective CABG, who were randomly divided into 2 groups. Anesthesia was induced and maintained with total intravenous anesthesia in both groups while intravenous PCA with morphine was administered in Group 1 and infusion of levobupivacaine was administered from the beginning of the anesthesia in Group 2 by thoracic epidural catheter...
