Moderate hypothermia may have a beneficial effect on the neurological outcome. However, ischemic deterioration such as brain swelling during rewarming has been reported as a notable complication after successful therapeutic cerebral hypothermia. In this study, we investigated the effects of hyperbaric oxygenation during rewarming. Forebrain ischemia was produced in 24 gerbils and sham ischemia ...

PURPOSE To analyze PCNA immunoexpression on the inferior pole of the spleen of splenectomized rats submitted to hyperbaric oxygenation (HBO). METHODS Were analyzed fragments of the inferior pole of the spleen of 20 male Wistar rats submitted to splenectomy with preservation of the inferior pole. The rats were divided in two groups: group A (n=10) without HBO and group B (n=10) submitted to HB...

BACKGROUND Cutaneous nonhealing ulceration is a threatening manifestation of vasculitis. Hyperbaric oxygen (HBO), frequently used as adjuvant therapy for patients with ischaemic ulcers, exerts additional beneficial effects on the vascular inflammatory response. AIM To evaluate the effect of HBO on vasculitis-induced nonhealing skin ulcers. METHODS The study population comprised 35 patients ...

AIMS To quantify retinal vascular change during and after hyperbaric oxygenation (HO) for 6x5 weekly 90 minute treatments. METHODS Fundus photographs were taken before, during, and after HO at 2.5 atmospheres absolute pressure (ATA) on days 1, 2, 3, 10, 20, 29, and 30 of treatment on three patients using a specially developed hand held ophthalmoscope with a digital colour camera. Blood vessel...

PURPOSE To evaluate the morphology, necrotic area and collagen content in skin flaps of rats subjected to hyperbaric oxygenation (HBO). METHODS Forty adult rats were divided into four groups: GEC - epilated; GE/HBO - epilated subjected to HBO; GER - epilated submitted to skin flap (2 cm in width /8 cm length in the dorsal area) and GER/HBO - epilated, subjected to skin flap and HBO. HBO (2.4 ...

INTRODUCTION AND OBJECTIVE In order to determine the effects of hyperbaric oxygenation, 14 Cuban children (8 boys and 6 girls) with affected lesions on the Central Nervous System (CNS), were prospectively studied between September 1994 and September 1995; the patients came from the external consultation of Neuropediatric of the Academic Pediatrics Hospital, Tuna Martyrs, Cuba. PATIENTS AND ME...

We studied a 4-year-old boy from Angola who presented with 2 cutaneous ulcerations of the right hip and osteomyelitis of the left knee and right ankle. Mycobacterium ulcerans disease was confirmed by direct smear examination and by polymerase chain reaction. The patient was treated with antimycobacterial drugs, repeated surgical debridement, skin grafting, and daily hyperbaric oxygenation. Desp...

BACKGROUND Pneumocephalus (PNC) is defined as a pathological collection of gas within the cranial cavity. The authors studied the effects of hyperbaric oxygenation (HBO2) therapy on a group of patients with PNC, comparing them with a control group to determine the relative impact on pneumocephalus volume, clinical symptoms, and duration of hospitalization. METHODS Twenty-four patients with PN...

The paper presents the review of the treatment performed in 183 patients with acute renal failure caused by trauma, myorenal syndrome, surgical, obstetric and urological lesions. All the patients underwent hemodialysis. The majority of the patients manifested hypoxia due to pulmonary edema and abnormal central and visceral hemodynamics, anemia resultant from blood loss and suppression of hemopo...

• Hyperbaric oxygenation has been reported to be beneficial in a variety of conditions characterized by ischemia. The rationale for its use in acute myocardial infarction, as in other ischemic conditions, depends on the fact that the amount of physically dissolved oxygen in the capillaries, and hence potentially available for the tissues, is directly related to its partial pressure in the capil...
