High-risk left main coronary artery bypass surgery supported by the Impella Recover LP 2.5 assist device: an alternative insertion technique.

Patients with high-risk coronary lesions such as left main stenosis and a severely depressed left ventricular ejection fraction are at risk of death and morbidity-related complications during coronary artery bypass surgery. Several alternative methods have been developed for managing this problem, but it is still challenging, even for highly experienced and well-equipped cardiac surgery centers. We report the case of a successful coronary artery bypass surgery supported by the Impella Recover LP 2.

Comparison of the effect of sevoflurane and halothane anesthesia on the fall in heart rate as a predictor of successful single shot caudal epidural in children.

Objective: To investigate the effect of sevoflurane anesthesia on heart rate HR fall with the injection of the initial drug in caudal space to confirm the correct needle placement.

Methods: After the ethical approval was obtained from the hospital's ethics committee, a prospective, randomized, clinical study was designed in Yeditepe University Hospital, in 2007. Children aged 1-12 years, scheduled for infraumbilical surgery under general anesthesia, and caudal block were included in the study.

Internal jugular vein diameter in pediatric patients: are the J-shaped guidewire diameters bigger than internal jugular vein? An evaluation with ultrasound.

Aim: This study investigates whether the diameters of right internal jugular vein (RIJV) are suitable for the use of 'big radius curved J-tip' Seldinger wires in pediatric patients.

Methods: One-hundred and thirty-five children, 1 month to 15 years of age, scheduled for pediatric surgery were divided into four subgroups according to their age (0-12 months, 1-2 years, 2-6 years old, and >6 years). Patients in the 0-12 months group were further divided into two groups as 0-6 months and 7-12 months of age to evaluate RIJV characteristics in detail.

The effect of 2 different concentrations of rectal ketamine on its premedicant features in children.

Objective: To investigate whether changing concentration and volume of ketamine for rectal premedication would change the premedication and recovery characteristics.

Methods: A prospective, randomized, clinical study was designed in Yeditepe University Hospital, Istanbul, Turkey in 2006-2007. The study group included children weighing 10-20 kg, American Society of Anesthesiologists grade I, scheduled for inguinal hernia repair or circumcision under general anesthesia with orotracheal intubation and caudal blockade.

Intraarticular tramadol plus pericapsular incisional bupivacaine provides better analgesia than intraarticular plus pericapsular incisional bupivacaine after outpatient arthroscopic partial meniscectomy.

Postoperative analgesic effects of intraarticular tramadol plus periarticular bupivacaine, and intraarticular plus periarticular bupivacaine injections after day-case arthroscopic partial meniscectomy were compared. Seventy-four ASA I/II patients undergoing arthroscopic partial meniscectomy, performed by a single surgeon under general anesthesia were assigned in a randomized, double-blinded manner into two groups: Group TB (n = 41) received intraarticular 100 mg of tramadol in 20 ml normal saline and periarticular incisional injection of 10 ml bupivacaine 0.5%.
