We report a case of rheumatic heart disease with severe mitral stenosis having cyanosis and low oxygen saturation on pulse oximetry. The findings of clinical examination and low values on pulse oximetry were inconsistent with the findings of normal partial pressure of oxygen and oxygen saturation on arterial blood gas analysis, leading to diagnostic dilemma. In such clinical scenario, the anest...

PURPOSE To determine the retinal oxygen saturation trend with onset of diabetes and increasing severity of diabetic retinopathy by comparing diabetic groups with and without retinopathy to controls. METHODS A fundus camera-based dual-wavelength snapshot oximeter imaged retinas of healthy subjects and patients with and without diabetic retinopathy. The images were analyzed to determine oxygen ...

We have evaluated three different devices for oxygen administration in the surgical ward, the Hudson face mask (oxygen 3 litre min-1, air 12 litre min-1), the nasal prong (oxygen 3 litre min-1) and the binasal catheter (oxygen 3 litre min-1). We evaluated the three devices in random order for periods of 30 min each in 25 patients with postoperative hypoxaemia (SpO2 < or = 94%). Arterial oxygen ...

OBJECTIVE To reduce hyperoxia in very low birth weight infants who receive supplemental oxygen, the Children's Mercy Hospital neonatal respiratory quality improvement committee introduced the potentially better practice of oxygen saturation targeting and identified strategies to overcome barriers to implementation of this practice. METHODS Using rapid-cycle quality improvement projects, this ...

background : due to the higher risk of  pain in preterm infants, pain management is important for such infants. the present study aimed to determine the effectiveness of kangaroo care on the severity of pain and physiological parameters after heel-stick in preterm infants. materials and methods: this was a prospective and randomized controlled cross-over study. twenty preterm infants allocated ...

BACKGROUND Perioperative disturbances of microvascular blood flow and oxygenation in the intestinal tract have been hypothesized to play an important role in development of the multiple organ dysfunction syndrome. Herein, increased intra-abdominal pressure (IAP) has been identified as a key factor in the initiation of the pathophysiologic cascade. The authors hypothesized that increasing the IA...

Objective- To assess the feasibility of splenectomy using intracorporeal ligature placement technique. Design- Randomized experimental study. Animals- Dogs (n=7) weighting≥ 20 kg. Procedures- Dogs were randomly selected. A lap-assisted splenectomy was performed. The feasibility of splenectomy was examined using intracorporeal ligatures. Comparisons were made regarding the anes...

BACKGROUND Liver transplant is the only definitive treatment for many patients with end stage liver disease. Presence and severity of preoperative pulmonary disease directly affect the rate of postoperative complications of the liver transplantation. Arterial blood gas (ABG) measurement, performed in many transplant centers, is considered as a traditional method to diagnose hypoxemia. Because A...

Commercial aquaculture is growing worldwide except in Africa where production is still low. With fisheries reaching a stagnating phase, the world and more so Africa will have to look to aquaculture in the future to provide fish products that will likely be needed. In view of this, a study on water quality management was done which specifically looked at the effects of dissolved oxygen saturatio...
