An Uncommon Cause of Low Oxygen Saturation in a Chinese Girl
نویسندگان
چکیده
Digital pulse oximetry is a useful non-invasive tool to monitor oxygen saturation. However, it has its own limitation and cannot reflect the true arterial oxygen saturation in case of unstable haemoglobin. We report a Chinese girl having unstable haemoglobin presenting with incidental finding of low oxygen saturation measured by pulse oximetry, its value in identifying affected family members and the importance of recognising unstable haemoglobin in patient with asymptomatic low oxygen saturation.

Unilateral and multiple nodular plexiform Neurofibromas: An uncommon presentation of Neurofibromatosis type 1
Plexiform neurofibroma is a rare variant but pathognomonic of von Recklinghausen disease. We report an uncommon presentation of neurofibromatosis type I in a girl. This 11-year old girl had multiple plexiform neurofibromas on her left hand, and also several Lisch’s nodules. Classification and clinical features are discussed briefly with emphasis on the possibility this condition may not be give...
متن کاملThe association between oxygen saturation and cataract disease and related factors in Birjand Vali-asr Hospital
Introduction: Any opacity of lens is defined as cataract. This leads to reduced vision that is the most common cause of blindness in the world in among the elderly. There is no non-surgical treatment for cataract patients; thereby, patients have to spend a lot of money especially those residing in the undeveloped countries. It is thus necessary to be informed of predisposing factors in order to...

Case: A 4-year old girl was examined with burns over her abdominal area and lower extremities. Her parents had applied opium on burned area to relieve her pain. She was in delirium state and apnea...
متن کاملAnesthetic experience of methemoglobinemia detected during general anesthesia for gastrectomy of advanced gastric cancer -A case report-
Methemoglobinemia is an uncommon but potentially fatal disorder. Most cases have no adverse clinical consequence and require no treatment, but methemoglobinemia is often overlooked as a cause of low oxygen saturation, and often mistaken for the more common causes of hypoxia by anesthesiologists despite simple bedside tests that indicate the presence of this treatable abnormality. We present a 6...
متن کاملEffects of position on oxygen saturation and heart rate in very low birth weight neonates
Background: Desirable oxygenation of preterm newborns has particular importance, for this reason different methods have been proposed to improve oxygenation of the newborns; one of these methods is the newborns' position. The aim of this study was to determine the effect of the position of low birth weight neonates on arterial oxygen saturation and heart rate. Methods: This interventional st...
