Airway management in general anesthesia for endovascular treatment of cerebral arteriovenous malformation: a retrospective observational study.

Background And Objective: This retrospective and observational study aimed to retrospectively evaluate the use of the endotracheal tube (ETT) and the Laryngeal Mask Airway (LMA) for the airway management with respect to airway safety, hemodynamic stability, adverse respiratory events, and recovery characteristics in patients who underwent endovascular treatment (EVT) for cerebrovascular arteriovenous malformation under general anesthesia between 2011 and 2018.

Methods: The study included data from the patient's electronic medical records and anesthesia files. The primary outcome measure was the incidence of hemodynamic disturbances and respiratory adverse events during airway management.

Comparison of three sitting positions for combined spinal - epidural anesthesia: a multicenter randomized controlled trial.

Background And Objectives: The aim of this prospective, multi-centered and multi-arm parallel randomized trial was to test the hypothesis that modified sitting positions including hamstring stretch position (HSP) and squatting position (SP) would reduce needle - bone contact events and increase the success rate of combined spinal - epidural anesthesia (CSEA) compared to traditional sitting position (TSP) in patients undergoing total knee or hip arthroplasty.

Patients And Methods: Three hundred and sixty American Society of Anesthesiologists (ASA) I-III patients, aged between 45-85 years were randomly allocated to one of three groups using computer-generated simple randomization: group TSP (n = 120), group HSP (n = 120), and group SP (n = 120). Primary outcome measures were the number of needle-bone contact and success rates.

[The relation between preoperative anxiety and awareness during anesthesia: an observational study].

Background: Anxiety is a state of worry caused by the anticipation of external or internal danger. Awareness During Anesthesia (ADA) is an unexpected memory recall during anesthesia. In this study, we aimed to determine the factors that affect preoperative anxiety and observe the incidence of ADA, as well as to determine the anxiety levels of these patients with a history of ADA.

Fast-track anesthesia in patients undergoing outpatient laparoscopic cholecystectomy: comparison of sevoflurane with total intravenous anesthesia.

Background: The use of short-acting anesthetics has introduced a "fast-track anesthesia" concept in outpatient surgery which provides discharge of the patients from operation room directly to the phase II recovery area without entering into postanesthesia care unit. The aim of this prospective and randomized study was to compare general anesthesia using sevoflurane with propofol-remifentanil-based total intravenous anesthesia (TIVA) for fast-track eligibility in patients undergoing outpatient laparoscopic cholecystectomy. The secondary aim was to compare 2 discharge scoring systems: White's Fast-Tracking Scoring System (WFTSS) and Modified Aldrete Scoring Systems (MASS) with regard to postanesthesia care unit bypass rate and postoperative problems.

What is Scientific Research and How Can it be Done?

Scientific researches are studies that should be systematically planned before performing them. In this review, classification and description of scientific studies, planning stage randomisation and bias are explained.

Tizanidine for the management of acute postoperative pain after inguinal hernia repair: A placebo-controlled double-blind trial.

Background: α2-Agonists are used postoperatively as a component of multimodal analgesia. Tizanidine is a centrally acting α2-agonist with muscle relaxant properties.

Objective: The aim of this study was to compare the efficacy of tizanidine with placebo in terms of postoperative pain scores, analgesic consumption, return to daily activity and health-related quality of life.

Do the patients read the informed consent?

Background: Informed consent is a process which consists of informing the patient about the medical interventions planned to be applied to the patient's body and making the patient active in the decision making process.

Aims: The aim of this study was to evaluate whether the patients read the informed consent document or not and if not, to determine why they did not read it. This was achieved via a questionnaire administered at the pre-anaesthetic visit to assess the perception of patients to the informed consent process.

Comparison of randomized preemptive dexketoprofen trometamol or placebo tablets to prevent withdrawal movement caused by rocuronium injection.

Rocuronium is a non-depolarizing neuromuscular blocking agent which is associated with injection pain and induces withdrawal movement of the injected hand or arm or generalized movements of the body after intravenous injection. The aim of this randomized study was to compare the efficacy of pretreatment with oral dexketoprofen trometamol (Arvelles(®); Group A) with placebo (Group P) without tourniquet to prevent the withdrawal response caused by rocuronium injection. The study cohort comprised 150 American Society of Anaesthesiologists class I-III patients aged 18-75 years who were scheduled to undergo elective surgery with general anesthesia.

Tracheal compression during shoulder arthroscopy in the beach-chair position.

Background: Respiratory distress is a rare complication of outpatient shoulder arthroscopy and mostly associated with general anesthesia, pneumothorax, anaphylaxis, or phrenic nerve paralysis.

Objective: We report on a shoulder arthroscopy complicated by tracheal compression caused by extravasation of irrigation fluid into soft tissues of the upper airway while the patient was in the beach-chair position under general anesthesia.

Case Summary: A 33-year-old male was scheduled for shoulder arthroscopy for impingement syndrome of the right shoulder under general anesthesia combined with interscalene brachial plexus block.
