Abstract: Microembolic signals (MES) are frequently observed by transcranial Doppler ultrasound after prosthetic heart valve implantation. Whether these MES are due to solid or gaseous particles is uncertain. We hypothesized that MES are gaseous and that if they are...

Hyperbaric Oxygen Therapy (HBOT) Research for Stroke
A comparison of the haemodynamic effects of intrathecal meperidine, meperidine-bupivacaine mixture and hyperbaric bupivacaine.
Abstract: To study the haemodynamic effects of intrathecal meperidine, administered either alone or mixed with bupivacaine. We studied 42 Chinese patients, aged 59-87 yr, scheduled for transurethral bladder or prostate surgery, randomized into three equals groups,...
Hyperbaric oxygen after global cerebral ischemia in rabbits reduces brain vascular permeability and blood flow.
Abstract: Hyperbaric oxygen (HBO) has been advocated as a therapy to improve neurological recovery after ischemia, since HBO may improve tissue oxygen delivery. We examined the effect of HBO treatment after global cerebral ischemia on early brain injury. Rabbits were...
Hypothermia and hyperbaric oxygen as treatment modalities for severe head injury.
Abstract: Moderate systemic hypothermia has been shown to improve neurologic outcomes in both fluid-percussion and cortical contusion models of experimental brain injury. Based upon initial clinical work, it was concluded that at temperatures < 32 degrees C, patients...
Hyperbaric oxygen in the treatment of acute ischemic stroke. A double-blind pilot study.
Abstract: The effects of hyperbaric oxygen (HBO) therapy on humans are uncertain. Our study aims first to outline the practical aspects and the safety of HBO treatment and then to evaluate the effect of HBO on long-term disability. Patients who experienced middle...
Cardiovascular deconditioning occurs during a 7-day saturation dive at 31 ATA.
Abstract: Cardiovascular deconditioning (CD) has been reported to occur within 24-48 h of exposure to 4, 11, or 31 ATA environment and following decompression to sea level pressure. The CD was indicated by orthostatic intolerance, exaggerated cardiovascular responses...
[Effects of hyperoxia regimes on the state of lipid peroxidation and hemostasis in patients with lesions of the central nervous system].
Abstract: Lipid peroxidation and some parameters of hemostasis were studied during exposure to various hyperoxia schemes combined with heparin therapy before and after treatment in 124 patients aged 16 to 69 with CNS involvement which developed as a result of...
Anesthetic and hemodynamic effects of single bolus versus incremental titration of hyperbaric spinal lidocaine through microcatheter.
Abstract: This study examined anesthetic development and hemodynamic changes during two techniques of hyperbaric lidocaine administration through 27-gauge intrathecal catheters for continuous spinal anesthesia in 55 elderly patients undergoing transurethral prostatic...
Influence of hyperbaric oxygen on left ventricular contractility, total coronary blood flow, and myocardial oxygen consumption in the conscious dog.
Abstract: It is known that hyperbaric oxygenation (HBO) decreases total coronary blood flow (TCBF) and cardiac output (CO). To determine whether this is related to an alteration in myocardial contractility, 10 chronically instrumented conscious dogs were studied...
