Objective. The aim of this prospective, randomized study was to investigate the effects of low-flow sevoflurane anesthesia on the pulmonary functions in patients undergoing laparoscopic cholecystectomy. Methods. Sixty American Society of Anesthesiologists (ASA) physical status classes I and II patients scheduled for elective laparoscopic cholecystectomy were included in the study. Patients were...

INTRODUCTION Using a novel method called near-infrared transillumination backscattering sounding (NIR-T/BSS) that allows for the non-invasive measurement of pial artery pulsation (cc-TQ) and subarachnoid width (sas-TQ) in humans, we assessed the influence of sympathetic activation on the cardiac and respiratory contribution to blood pressure (BP) cc-TQ oscillations in healthy subjects. METHOD...

Background: Chest compression with adequate depth and number is one of the main indicators of high-quality cardiopulmonary resuscitation (CPR). Nevertheless, no proper counting technique is suggested to provide sufficient number of massages. Aim: To compare the effects of three techniques of chest compression counting on the quality of CPR and rescuer fatigue. Method: Inthis clinical trial, 30 ...

OBJECTIVES At present, there is no standard bedside method for assessing cerebral autoregulation (CA) with high temporal resolution. We combined the two methods most commonly used for this purpose, transcranial Doppler sonography (TCD, macro-circulation level), and near-infrared spectroscopy (NIRS, micro-circulation level), in an attempt to identify the most promising approach. METHODS In eig...

Background The use of anesthetic drugs with minimal inhibitory effects on the hypoxic pulmonary vasoconstriction (HPV) could have a decisive role in preventing the hypoxemia during one-lung ventilation (OLV). Objective The aim of this study was to compare the effects of propofol and isoflurane on the changes in gas exchange parameters following OLV in thoracic surgery. Methods This double-b...

Key points The cerebral fluid response to exercise, including the arterial and venous blood flow (CBF) cerebrospinal (CSF), currently remains unknown. We used time-resolved phase-contrast magnetic resonance imaging assess changes in CBF CSF dynamics during moderate-intensity rhythmic handgrip (RHG) exercise young healthy men women. Our data demonstrated that RHG increases inflow outflow while d...

Prone positioning (PP) was shown to reduce mortality in mechanically ventilated (MV) patients with severe ARDS [1]. Despite its common use, safety concerns inhibit use of flexible bronchoscopy (FB) in patients with ARDS, and there are few reports of FB performed in PP [2]. We reviewed all adults receiving FB in PP in one institution between April 2016 and September 2017. The study was approved ...

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...
