Patient with Wolff-Parkinson-White syndrome with intermittent pre-excitation under subarachnoid block for urological surgery

Infraclavicular Brachial Plexus Block and Sugammadex Use in a Paediatric Patient with Wolff-Parkinson--White Syndrome

Background

Wolff–Parkinson–White (WPW) syndrome is a rare disease that can cause various patterns of tachyarrhythmias. The main goal of anaesthesiologists for the perioperative anaesthetic management of WPW patients must be to avoid sympathetic stimulation and prevent tachyarrhythmias.

Case

A 9-year-old male patient with a diagnosis of WPW syndrome, who underwent emergency surgery for supracondylar humerus fracture, is presented. General anaesthesia in combination with infraclavicular brachial plexus (ICBP) block was performed successfully without any complications. For the reversal of neuromuscular block, sugammadex was uneventfully used. Intraoperative sympathetic discharge due to surgical intervention was prevented with ICBP block. The ICBP block has also provided good postoperative analgesia.

Conclusions

Sugammadex is a good alternative for the reversal of neuromuscular blocks to avoid the undesirable effects of cholinergic drugs. Peripheral regional blocks that require relatively large doses of local anaesthetics can be safely performed with utmost attention in paediatric WPW patients.

Perioperative management of patients with pre-excitation syndromes

Patients with pre-excitation abnormalities are at a high risk for life-threatening perioperative arrhythmias. In Wolff-Parkinson-White syndrome, the anaesthetics used for invasive diagnostic testing/ablation, should not affect cardiac electrophysiology; propofol, sevoflurane, fentanyl, sufentanil, alfentanil are suitable. In non-ablative surgery, propofol, sevoflurane, isoflurane, fentanyl, alfentanil, sufentanil have been used safely. Among neuromuscular blockers, cis-atracurium, rocuronium and vecuronium are good choices. Ketamine, pancuronium and pethidine should be avoided because of their sympathomimetic actions. Anticholinergic/ anticholinesterase combinations for neuromuscular block reversal should preferably be omitted, while sugammadex seems more attractive. In regional anaesthesia, addition of epinephrine and high sympathetic blocks should be avoided. Hypotension should be treated with pure alpha-adrenergic agonists. Other pre-excitation abnormalities associated with different accessory pathways are the Mahaim Fiber and Lown-Ganong-Levine syndrome. Sympathetic activation should be avoided. Total intravenous anaesthesia with propofol probably represents the safest option. A careful anaesthetic plan and close cooperation with cardiologists are mandatory for successful management.

Spinal Anaesthesia is Safe in a Patient with Wolff-Parkinson-White Syndrome Undergoing Evacuation of Molar Pregnancy

Wolff-Parkinson-White (WPW) syndrome is an uncommon cardiac condition where there is an abnormal band of atrial tissue connecting atria and ventricles which can electrically bypass atrioventricular node. The anaesthetic management in these patients is challenging as life threatening complications can occur perioperatively like paroxysmal supraventricular tachycardia and atrial fibrillation. Also, regional anaesthetic technique like subarachnoid block is a safe and cost effective alternative to general anaesthesia as it avoids polypharmacy. We report the successful anaesthetic management of Wolff Parkinson White syndrome in a primi with hydatiform mole posted for suction and evacuation.
