Effects of Changes in Body Temperature on Perioperative Bleeding in Adolescent Idiopathic Scoliosis Surgery.

Perioperative bleeding is a critical challenge in adolescent idiopathic scoliosis (AIS) surgery. Preventing hypothermia is associated with decreased development of coagulopathy, blood transfusion rate in various surgery groups. We hypothesized that blood loss would be reduced in patients who were kept normothermic by implementation of aggressive warming methods in AIS. This randomized-controlled study included patients aged 12-18 years who were scheduled to undergo elective scoliosis deformity correction surgery. The patients were divided into two groups: the study group (Group S) was heated aggressively with three different heaters including compressed-air blower heater, intravenous fluid heating, and a heating bed, while the control group (Group C) received only heating with a standard compressed-air blower heater. Tympanic, esophageal, and axillary body temperatures were measured, and hemoglobin and arterial blood gas analyses were repeated during the anesthesia period. Daily bleeding-coagulation parameters were recorded on postoperative days 0, 1, and 2. Forty-eight patients were randomized, and 39 patients were included into the final analysis. The total amount of intraoperative bleeding (p = 0.027) was significantly lower, and duration of surgery (p = 0.025) and length of hospital stay (p = 0.002) were significantly shorter in Group S. Significant linear relationships were found between the core body temperature and the amount of bleeding (ß = 0.0001; p = 0.009), operation time (ß = 0.003; p = 0.015), and length of hospital stay (ß = 0.027; p = 0.044) with linear logistic regression analysis. We reported that normothermia was preserved in the multiheated group, which diminished blood loss, operation time, and the length of hospital stay. Consequently, we suggested that active heating should be applied in AIS surgeries. ClinicalTrials.gov (NCT04686214).

Anesthetic management of scoliosis operation in a pediatric patient with Frank-ter Haar syndrome: a case report.

Frank-ter Haar syndrome is a rare disorder characterized by multiple skeletal, cardiovascular abnormalities, and facial features. Some of these characteristic facial features are important for anesthesiologists to predict the difficult airway. We present the anesthesia management of an 8-year-old boy with Frank-ter Haar syndrome who underwent posterior spinal instrumentation operation for scoliosis. In these patients, it is vital to anticipate possible difficult intubation before surgery and make all necessary preparations.

Brachial Plexus Injury Associated With Subclavian Vein Cannulation: A Case Report.

We documented brachial plexus injury by electromyography and magnetic resonance imaging secondary to needle sticks for central line insertion. This type of complication is rare in the literature, as few case reports exist. Brachial plexus injury can happen because of anatomic variations. Nevertheless, multiple attempts or introducer needle rotations should be avoided during subclavian vein catheterization. Pain that emerges in the ipsilateral arm after subclavian catheter placement should be taken into serious consideration. It is important to identify the cause of pain as soon as possible so that the correct treatment can be efficiently provided. Use of an ultrasound-guided catheterization may be a better choice for preventing complications.
