Introduction :
Undersea & Hyperbaric Medical Society (2024) has defined hyperbaric oxygen treatments (HBOT) as a medical procedure that patients have their entire body within a hard sided hyperbaric chamber meeting the standard of ASME-PVHO-1 and NFPA99, at the pressure not less than 2.0 ATA while breathing medical grade oxygen for typically 90-120 minutes. With confined space, change of pressure during treatment and high dose of oxygen, few adverse effects of HBOT have been identified, including ear barotrauma, sinus barotrauma, hypoglycemia, oxygen induced seizure and claustrophobia etc. (Zhang et al, 2023)
Objectives :
1. To review and analyze the patient events happened in Pamela Youde Nethersole Eastern Hospital (PYNEH) Hyperbaric Oxygen Therapy Centre (HBOTC)
Methodology :
3656 patient episodes of HBOT in Pamela Youde Nethersole Eastern Hospital (PYNEH) Hyperbaric Oxygen Therapy Centre (HBOTC) during Year 2023 were reviewed. The events happened during these patient episodes were analyzed.
Result & Outcome :
In these 3656 patient episodes of hyperbaric oxygen treatments, there were 37 patient events (1.01%). Among of them, ear barotrauma is the most common event (N=28, 0.77%). Besides, there were one episode of hypoglycemia (0.03%) and one episode of seizure (0.03%). Apart from those mentioned, there were 7 events, which include acute retention of urine and chest pain etc, that have no obvious relationship with HBOT. Besides, there were no event of lung or sinus barotrauma and claustrophobia.
Comparing with the data from 11 Australian hyperbaric centres (retrieved from Hyperbaric Technicians and Nurses Association) in Year 2022-2023, the ear barotrauma is also the most common one (0-1.45%). The seizure rate ranged from 0% - 0.07% and the hypoglycemia rate ranged from 0% - 0.54%.
Conclusions:
With reference to the Australian data, the complication rate of HBOT in PYNEH HBOTC is similar or less. It is suggested that the patient safety in PYNEH HBOTC is comparable with international standard.
