Background: Induction of anesthesia in patients that undergo cardiac surgery has more risk than others, because of specific cardiovascular effects of the anesthetic drugs and the preoperative state of these patients, so the hemodynamic stability is very important in these patients. It seems that midazolam have less cardiovascular side effects than thiopentone. In this study, the effects of mid...

Background: For spinal anesthesia, levobupivacaine is considered an effective alternative anaesthetic agent to conventional bupivacaineowing the faster recovery profile and lower probability of cardiovascular toxicity.Aim: To comparatively assess analgesic hemodynamic features dose hyperbaric bupivacaine isobariclevobupivacaine used for infra umbilical surgeries.Methods: The present clinical st...

background: keeping the patient in a sitting or semi-sitting position for time-consuming oncoplastic breast surgery is a major challenge for anesthesiologists due to several considerations. this cohort study was conducted on two groups of patients undergoing breast surgery. methods: study participants were categorized into two groups: one group was composed of normotensive women (group a) and t...

therefore their side-effects on these systems could be reduced by administering a combination of them at a lower dose.[9] In recent studies done on patients undergoing ECT, it showed that using sub-anesthetic ketamine and low-dose propofol could increase the seizure duration, provide hemodynamic stability and earlier recovery compared with the use of a full dose of propofol alone. In a study by...

BACKGROUND Lumbar plexus block (LPB) is one of the anesthetic options in the elderly patients undergoing hip surgeries. LPB could be safe because it targets somatic nerve in psoas region. Effectiveness of LPB is attributed to the sufficient analgesia provided intraoperatively as well as postoperatively. Adequate muscle relaxation and immobility during surgery refers to its acceptability. OBJE...

BACKGROUND Tourniquets are used to provide a bloodless surgical field for extremities. Hypotension due to vasodilation and bleeding after tourniquet deflation is a common event. Hemodynamic stability is modulated by the autonomic nervous system (ANS). Heart rate variability (HRV) is a sensitive method for detecting individuals who may be at risk of hemodynamic instability during general anesthe...

OBJECTIVE To determine if computed tomographic (CT) scanning can be used to identify patients with blunt trauma, positive results of diagnostic peritoneal lavage (DPL), and a stable hemodynamic status who could be managed safely and cost-effectively without celiotomy. DESIGN Patients with blunt trauma who required an abdominal evaluation underwent DPL. Patients with a red blood cell count gre...

INTRODUCTION Preterm birth is the most important univariant risk factor of neonatal mortality. Assessment of risk factors affecting mortality in preterm infants with very low birth weight is important for the treatment of this highly vulnerable population. OBJECTIVE Detection of risk factors for neonatal mortality in very low birth weight premature infants. METHODS The current study was con...

BACKGROUND AND OBJECTIVES Dexmedetomidine, alpha2-adrenergic agonist with alpha1:alpha2 specificity of 1:1620, does not promote respiratory depression and is intraoperatively used for sedation and analgesia. It has been used associated to opioids in anesthesia for procedures with high painful stimulation, such as intraperitoneal surgeries, and there are no references to its use as single agent....

BACKGROUND AND OBJECTIVES There are no studies associating ventilation-induced effects and hemodynamic changes during pneumoperitoneum. This study aimed at evaluating hemodynamic changes determined by pneumoperitoneum in dogs under volume and pressure controlled ventilation. METHODS The study involved 16 dogs anesthetized with sodium thiopental and fentanyl, divided in group 1: volume control...
