was attributed to the broncho-pneumonia, but against this explanation was the fact that the administration of oxygen failed to abolish or decrease the cyanosis, whereas the cyanosis usually accompanying bronchopneumonia can be relieved or abolished easily by adding some oxygen to the inspired air." He suggested, on the evidence that he gave, that the haemoglobin was in the form of methaemoglobi...

Hemoglobin (Hb) Kansas is an inherited Hb variant with a low oxygen affinity that is associated with low oxygen saturation on pulse oximetry (SpO2). It leads to asymptomatic cyanosis. Patients with Hb Kansas do not require any specific treatment and the prognosis is good. In patients with unexplained cyanosis, we should thus consider Hb variants, including Hb Kansas and avoid unnecessary invest...

Five-day-old male neonate born to non-consanguineous parents by normal vaginal delivery was presented with deformity of lip, face and eyelid on the right side, and cyanosis. The cyanosis had improved soon after endotracheal intubation. Examination revealed deformity of upper lip, upper jaw and lower eyelid of right eye; this type of craniofacial cleft is called as Tessier type 3 (Fig. 1). There...

Preoperative care includes a clinical examination before invasive or non-invasive interventions for anaesthesia/analgesia and is the responsibility of the anaesthesiologists. Methemoglobinemia should be considered, as well as cardiac, pulmonary, and peripheral circulatory disorders in patients with central cyanosis and low oxygen saturation despite treatment with sufficient oxygen during anaest...

Progressive cyanosis often develops following Kawashima operation in patients with left atrial isomerism, interrupted inferior vena cava and hepatic veins draining to the atria. Knowledge on the timing and extend of resolution following hepatic venous redirection is sparse. A girl developed progressing cyanosis following Kawashima operation at the age of ten months. Arterial oxygen saturations ...

Pulmonary arteriovenous fisula is a rare condition in which there is abnormal connection between pulmonary arteries and veins. We describe this condition is an 18-year-old male who presented with cyanosis, clubbing, polycythemia and multiple brain abscesses. The patient was diagnosed as pulmonary arteriovenous fistula based on CT scan and on pulmonary angiography. The patient had a complete rec...
