“…Dysfunction of devices used to deliver these drugs during hyperbaric oxygen therapy may compromise their safety. Studies, case reports and letters have demonstrated the problems associated with specific infusion devices [4][5][6][7][8][9][10][11][12], which we have replicated in our institution (unpublished results). Some devices fail completely at normal treatment pressures [6,7,11], whereas others deliver inconsistent flow rates.…”

SummaryHaemodynamic instability is a recognised phenomenon in critically ill patients undergoing hyperbaric therapy. Instability may result from the effects of ambient pressure on the cardiovascular system, devices involved in infusion of drugs and fluids, or a combination of the two. The effect of hyperbaric pressure on air-containing spaces in syringes has not been previously measured. We connected 60-ml syringes (Terumo Corporation, Tokyo, Japan) containing coloured water to low volume extensions via three-way taps. We examined the effect of pressurisation to 2.4 and 2.8 atmospheres absolute (ATA) on the syringes by measuring the displacement of the coloured water in the low volume extension set. There was compression of air spaces within the syringe causing retrograde flow of fluid within the low volume extension set. The mean (95% CI) change in volume was 154 (141-168) ll at 2. 4 ATA,[197][198][199][200][201][202][203][204][205][206][207][208][209][210][211][212] ll at 2

“…Most infusion pumps are unacceptable for use under hyperbaric conditions. 24 Safe HBOT for a critically-ill infant requires sufficient specially trained personnel; here this comprised an adult intensive care nurse, a pediatric respiratory therapist and a hyperbaric physician inside and a hyperbaric physician, adult critical care nurse, pediatric intensive care nurse, pediatric intensivist and technical staff (supervisor and chamber operator) outside the chamber.…”

P Pu ur rp po os se e: : Infants with cyanotic congenital heart disease are at risk for cerebral arterial gas embolism (CAGE) from iv infusion lines. Concern about the hazards and difficulty of caring for such patients inside a hyperbaric chamber may deter referral. We report a complex case in which a small infant was managed successfully using a modified hyperbaric oxygen treatment (HBOT) schedule.C Cl li in ni ic ca al l f fe ea at tu ur re es s: : A four-month-old 6.19 kg male infant with a recent Glenn shunt for double-outlet right ventricle had a seizure and became unstable immediately after an iv drug infusion. The patient was sedated, intubated and ventilated and dobutamine was commenced. A computerized tomography (CT) scan performed ten hours later demonstrated three intracranial air bubbles. About ten hours later the patient was referred for HBOT which commenced soon afterwards in a multiplace chamber. Since the rightto-left shunt would greatly increase the risk of decompression illness from breathing hyperbaric air HBOT was modified by the use of an abbreviated schedule at reduced pressure. Two 90-min HBOT sessions were administered within 24 hr at 38 feet of seawater pressure, equivalent to 2.15 atmospheres absolute without any air break. During treatment the infant was ventilated using an Oxford Penlon ventilator. A subsequent CT scan demonstrated the absence of air. After extubation he appeared neurologically intact except for some weakness of the left arm.C Co on nc cl lu us si io on n: : Hyperbaric oxygen may be utilized to treat CAGE in small infants with right-to-left shunt and should be commenced promptly.

“…It may be possible to use infusion pumps under hyperbaric conditions in patients with anaerobic infection, 7 arteriosclerotic obliteration, or a critical condition such as carbon monoxide poisoning. 8 There is a report on the performance of infusion pumps under hyperbaric conditions, 8 and it is concluded that commercially available infusion pumps operating under hyperbaric conditions demonstrated substantial variations in performance and accuracy. We are exposed to changes in atmospheric pressure in daily life.…”
