Knowledge and Views of Paediatricians about Pulse Oximetry: a Nationwide Online Survey in Nigeria

Pulse oximetry is a non-invasive method of measuring oxygen saturation in clinical settings. This study was carried out to determine the level of knowledge and competencies relating to pulse oximetry and the ability to interpret the information.We conducted a nationwide, multi-centre, and questionnaire-based online survey between January and June 2010. A 32-item questionnaire relating to the use of pulse oximetry in children was answered by 224 in-training and 157 qualified paediatricians (median duration of practice 6 years) working in 24 states in Nigeria. Knowledge of pulse oximetry was evaluated on a scale of 0­100%. Data were analysed using Chisquare and t-test statistics at 5% level of significance.The overall mean test score was 36.6±20.8% (range0­76.5%). The mean knowledge score among intraining and qualified paediatricians was 35.4±19.1%and38.3±23.1%,respectively(p>0.05). Only 16.3% of the respondents answered all three questions correctly relating to the relationship between oxygen saturationand partial pressure of oxygen. Pertaining to the accuracy of pulse oximeters, 3.9% of the respondents answered all 14 questions correctly. On indications for use of pulse oximetry, 29% correctly answered all nine questions. Only 18% of respondents correctly answered the seven questions on interpretation of pulse oximeter reading. Some 73% of respondents believed that training in the use of pulse oximetry was inadequate.A significant proportion of the paediatricians were untrained in pulse oximetry, lacked knowledge of basic principles, and made serious errors in interpretation of readings from pulse oximeters. We suggest that medical schools and residency training programmes place more emphasis on teaching the principles and uses of pulse oximetry

Choledochal cysts in African infants: a report of 3 cases and a review of the literature.

Choledochal cysts are relatively rare and are an uncommon cause of cholestasis. Early diagnosis and prompt treatment can prevent complications such as cholangitis, cirrhosis and portal hypertension. This article reviews a rarely reported disease in Africans in whom only 3 cases were documented over the 18 year period in Nigeria. The 3 cases were all females with ages between less than a month and 13 months at presentation. All presented with abdominal swelling with or without jaundice or acholic stools. The use of real-time ultrasonography antenatally and postnatally aided the diagnosis in our patients. Two of the patients presented and were operated and both made full recovery confirming the importance of early surgical intervention. The third patient died, and exemplified the consequences of delayed diagnosis and treatment which occur not uncommonly in developing countries mostly because of sparse and or expensive tertiary health care facilities.
