Decompression Illness Treated with the Hart-Kindwall Protocol in a Monoplace Chamber.

Abstract

Patient: Male, 34-year-old Final Diagnosis: Decompression illness Symptoms: Chest pain • mild cognitive impairment • paresthesia Medication: — Clinical Procedure: — Specialty: Critical Care Medicine Objective: Management of emergency care Background:Hyperbaric oxygen (HBO2) therapy in a multiplace chamber is the standard treatment for severe altitude decompression illness (DCI). However, some hospitals may only have a monoplace chamber. Herein, we present the case of a patient with severe altitude DCI caused by rapid decompression during an actual flight operation that was successfully treated through emergency HBO2 therapy with the Hart-Kindwall protocol, a no-air-break tables with the minimal-pressure oxygen approach in a monoplace chamber due to unavailability of rapid access to a multiplace chamber.Case Report:A 34-year-old male aviator presented with chest pain, paresthesia, and mild cognitive impairment following rapid decompression 20 minutes after take-off, which comprised 10 minutes of reaching a height of 10 058 m (33 000 feet) and 10 minutes of cruising at that altitude. He then initiated flight descent and landing. He visited a primary clinic, and severe DCI was suggested clinically. However, since the closest hospital with a multiplace chamber was a 3-hour drive away, we provided emergency HBO2 therapy with the Hart-Kindwall protocol in a monoplace chamber at a nearby hospital 4 hours after the initial decompression. He recovered fully and returned to flight duty 2 weeks later.Conclusions:Emergency HBO2 therapy with the Hart-Kindwall protocol in a monoplace chamber may be a suitable option for severe DCI, especially in remote locations with no access to facilities with a multiplace chamber. However, prior logistical coordination must be established to transfer patients to hospitals with multiplace chambers if their symptoms do not resolve.
