OBJECTIVE In this study of preterm neonates of <32 weeks, we prospectively compared the use of room air versus 100% oxygen as the initial resuscitation gas. METHODS A 2-center, prospective, randomized, controlled trial of neonates with gestational ages of 23 to 32 weeks who required resuscitation was performed. The oxygen group was initially resuscitated with 100% oxygen, with decreases in th...

A case is reported where reduced oxygen saturationwas detected bya pulse oximeter before clinical signs of pulmonary oedema appeared. A 45 years old, 82 kilogram lady presented for emergency surgery with subacute intestinal obstruction. She had no previous history of any cardiovascular, respiratory or metabolic disorder. She underwent partial colectomy and colostomy. Two days later she was agai...

BACKGROUND/AIMS We aimed to investigate whether endoscopy or midazolam as premedication causes oxygen desaturation and to determine factors which may affect the occurrence of oxygen desaturation. METHODS Totally 200 patients with various indications (103 men and 97 women), who presented to the Endoscopy Unit of Dicle University Hospital for upper gastrointestinal endoscopy examination, were i...

EXECUTIVE SUMMARY Philosophy of the guideline ✓ Oxygen is a treatment for hypoxaemia, not breathlessness. Oxygen has not been proven to have any consistent effect on the sensation of breathlessness in nonhypoxaemic patients. ✓ The essence of this guideline can be summarised simply as a requirement for oxygen to be prescribed according to a target saturation range and for those who administer ox...

To investigate the effects of supplemental oxygen on cardiac rhythm during gastroscopy, 103 patients aged over 60 were randomised to receive either supplemental oxygen or air at 2 litres/minute during the procedure. Pulse rate, blood pressure, oxygen saturation, and a Holter cardiac trace were monitored before, during, and for one hour after the gastroscopy. A wide range of electrocardiographic...

OBJECTIVE To determine the effects of temazepam on the quality of sleep and on oxygen saturation during sleep in subjects at high altitude. DESIGN Randomised, blinded, crossover, placebo controlled trial. SETTING Base camp at Mount Everest (altitude 5300 m). SUBJECTS 11 members of British Mount Everest Medical Expedition recently arrived at base camp. INTERVENTION Participants were rand...

Background The change in venous oxygen saturation occurs earlier, and even its reduction is faster than arterial oxygen saturation. The aim of this study was to validate SvO2 and PvO2 for O2 content measurement in children hospitalized w...

Intrathecal meperidine administration can provide surgical anaesthesia and postoperative analgesia for about two to six hours. We have observed two cases of respiratory depression associated with meperidine spinal anaesthesia. An 81-yr-old woman received 50 mg intrathecal meperidine for inguinal hernia repair. Supplemental oxygen was administered at 3 L.min-1 by nasal prongs. About 40 min later...

background and objectives: pulse oximetry is the most common technique for monitoring hemoglobin oxygen saturation (spo2). different colors and brands of nail polish may cause disturbance in the reading and interpretation of oxygen saturation. the aim of this study was to determine the effect of different colors of nail polish on oxygen saturation measured by pulse oximeter. methods: thirty hea...
