A&A practice

We present the case of a patient with a subcutaneous implantable cardioverter-defibrillator (S-ICD) in situ. Device interrogation and reprogramming were unsuccessful due to a software mismatch between the device and programmer. ⋯ The S-ICD has unique perioperative considerations for the anesthesiologist. This case provides an example of the complexity of electrophysiologic devices in current use and the necessity of the anesthesia provider to stay up to date with evolving device management strategies.

Thoracolumbar interfascial plane block (TLIPB) has recently been described for postoperative analgesia after thoracolumbar spine surgery. This block is minimally invasive, relatively safe, and easy to perform. ⋯ We describe the sonoanatomic landmarks of this technique, and we report results of this retrospective case series on analgesic impact of this block in patients undergoing implantation of spinal cord stimulation systems. Clinical studies are required to investigate the analgesic role of TLIPB for spinal thoracolumbar surgery.

Case Reports
Transesophageal Echocardiography-Guided Cardiopulmonary Resuscitation After Rocuronium Anaphylaxis.
Anaphylaxis is a life-threatening hypersensitivity reaction that can quickly progress to circulatory collapse, even in the presence of timely epinephrine administration. This report describes a case of rocuronium anaphylaxis which progressed to circulatory arrest despite intravenous epinephrine and crystalloid resuscitation. Transesophageal echocardiography performed during cardiopulmonary resuscitation enabled rapid identification of the cause of shock and redirected management to prioritize further fluid administration, leading to return of spontaneous circulation with a good outcome. The etiology of shock in anaphylaxis can be variable, and transesophageal echocardiography can rapidly identify the likely mechanism and guide treatment without interrupting ongoing resuscitative efforts.

Continuous regional analgesia techniques for ambulatory management of postoperative thoracic and abdominal wall pain are limited. We report the placement of an erector spinae plane (ESP) catheter in a pediatric patient who underwent rib resection for slipping rib syndrome and was discharged on postoperative day 1 with an elastomeric pump for continued regional analgesia in the ambulatory setting. The patient required minimal opioids while the catheter was in place and experienced a functional level that surpassed her preoperative state. Ambulatory ESP peripheral nerve catheters are a feasible and potentially effective option for the treatment of acute postsurgical pain in children.

A 70-year-old Jehovah's Witness was treated with iron carboxymaltose intravenously, recombinant human erythropoietin alpha subcutaneously, and vitamin B12 and folate orally for 9 weeks to raise hemoglobin (Hb) from 10.8 to 17.0 g/dL before explantation of an infected hip joint prosthesis. The target Hb was calculated from the following formula: Hbtarget = Hbfinal/(1 - ABL/EBV), where Hbtarget= Hb to achieve before surgery, Hbfinal = lowest Hb patient could tolerate taking into consideration his comorbidities (7 g/dL), ABL = volume of blood the surgeon estimated the patient would lose intra- and postoperatively (3000 mL), and EBV = estimated blood volume (75 mL/kg for an adult man). Spinal anesthesia was provided with a single shot hyperbaric bupivacaine and fentanyl. ⋯ Surgical blood loss was estimated to be 2500 mL. Hb at the end of surgery was 13.3 g/dL; on postoperative day 5, 11.7 g/L. No blood products were utilized.
