Peripheral Nerve Block for PD Catheter Insertion in a Pediatric Patient with Decompensated Heart Failure: A Case Report.

Peripheral nerve block (PNB) has been successfully used as the sole anesthetic for Peritoneal dialysis (PD) catheter insertion, and has been shown to provide satisfactory anesthesia and analgesia perioperatively, especially among critically-ill patients. This report describes the anesthetic management of an 18 - year old underweight pediatric patient with End-stage renal disease (ESRD) and decompensated heart failure who was scheduled for PD catheter insertion. He was given a left lateral Transversus abdominis plane (TAP) block and a right Rectus sheath (RS) block as the main anesthetic. Fifteen mL of Isobaric Bupivacaine 0.375% with Epinephrine 1:400,000 dilution was injected for the TAP block, and 10mL for the RS block, for a total volume of 25mL (93.7mg). Sedation was given via a Remifentanil infusion at 0.1mcg/kg/min. Intraoperatively, the patient was awake, conversant, and comfortable, no pressors were used, and no conversion to general anesthesia was done. Post-operatively, he had good pain control, with a pain score of 1/10, and successfully underwent dialysis via the PD catheter on the 2nd hospital day. This pediatric patient who is critically-ill is not a good candidate for general or neuraxial anesthesia due to the risk of hemodynamic instability and perioperative decompensation. PNB was done to provide satisfactory anesthesia, and ensure good pain control post-operatively, and left TAP and right RS blocks were done instead of a bilateral TAP to lower the LA volume and decrease the risk of LA toxicity. Unilateral TAP with contralateral RS is a safe anesthetic technique among critically-ill pediatric patients who will undergo PD catheter insertion without the risk of hemodynamic instability with general or neuraxial anesthesia, and to decrease the risk of LA toxicity.
