The effect of postoperative serratus anterior plane block on postoperative analgesia in patients undergoing breast surgery.

Objectives: This study aimed to evaluate the effect of serratus anterior plane block (SAP) on postoperative morphine consumption. We aimed to determine the differences between both similar blocks and evaluate the effect of the methods of application of this block on patients' postoperative pain scores and morphine consumption.

Material And Methods: This study is a single-center, prospective and observational study performed with 40 volunteer patients with American Society of Anesthesiologists (ASA) I-III, who were 18-70 years of age, scheduled for breast surgery.

An unusual condition during internal jugular vein catheterisation: vertebral artery catheterisation.

Vertebral artery cannulation is an unusual complication during internal jugular vein cannulation. We report a case of vertebral artery cannulation, which occurred during an attempt to cannulate the right internal jugular vein, and we discuss the management of such a rare complication.

The Effects of Bispectral Index and Neuromuscular Blockade Monitoring on the Depth of Anaesthesia and Recovery in Cardiac Patients Under Desflurane Anaesthesia.

Objective: In this study, we aimed to investigate the effects of bispectral index (BIS) and neuromuscular blockade monitoring on the depth of anaesthesia and recovery in cardiac patients, scheduled to undergo open cholecystectomy operation with desflurane anaesthesia.

Methods: After the approval of the Ethics Committee and consent from the patients, patients were randomly divided into two groups. All patients received standard induction drugs, and 4-6% desflurane was used for maintenance of anaesthesia.

Comparison of the effects of desflurane and sevoflurane on middle ear pressure: a randomized controlled clinical trial.

Objective: The aim of the present study was to compare the effects of two inhalation anesthetics, desflurane and sevoflurane, on middle ear pressure.

Methods: After we obtained written consent from the patients and the approval from our institutional ethical committee, we included 56 ASA I-II patients aged between 18 and 60 years in this study. They were randomly divided into two groups of 28 patients each.

The importance of needle echogenity in ultrasound guided axillary brachial plexus block: a randomized controlled clinical study.

Objective: In this study we aimed to compare the echogenic needles and the nerve stimulation addition to non-echogenic needles in ultrasound guided axillary brachial plexus block for upper extremity surgery.

Methods: 90 patients were enrolled to the study. The patients were allocated into three groups randomly: Group E (n=30): ultrasound guided axillary block using echogenic needle, Group N (n=30): ultrasound guided axillary block using non-echogenic needle, Group NS (n=30): ultrasound guided axillary block using non-echogenic needle with nerve stimulator assistance.
