Supplementation of pre-oxygenation in morbidly obese patients using nasopharyngeal oxygen insufflation

Nasopharyngeal oxygen insufflation following pre-oxygenation using the four deep breath technique.

This paper evaluates the effectiveness of nasopharyngeal oxygen insufflation following preoxygenation using the four deep breath technique within 30 s, on the onset of haemoglobin desaturation during the subsequent apnoea. Thirty ASA I or II patients were randomly allocated to one of two groups. In the study group (n = 15), pre-oxygenation was followed by insufflation of oxygen at a flow of 5 l...

Perioperative lung protection for obese patients EFFECTIVE PRE-OXYGENATION AND INDUCTION IN OBESE PATIENTS

Supplemental postoperative oxygen and tissue oxygen tension in morbidly obese patients.

BACKGROUND Subcutaneous tissue oxygen tension (PsqO(2)) is a major predictor for wound healing and the occurrence of wound infections. Perioperative subcutaneous wound and tissue oxygen tension is significantly reduced in morbidly obese patients. Even during intraoperative supplemental oxygen administration, PsqO(2) remains low. Tissue hypoxia is pronounced during surgery and might explain the ...

Smoking among morbidly obese patients

BACKGROUND Smokers usually have a lower Body Mass Index (BMI) when compared to non-smokers. Such a relationship, however, has not been fully studied in obese and morbidly obese patients. The objective of this study was to evaluate the relationship between smoking and BMI among obese and morbidly obese subjects. METHODS In a case-control study design, 1022 individuals of both genders, 18-65 ye...

PEG tube placement in morbidly obese patients.

We present two patients both of whom had severe morbid obesity and needed placement of a percutaneous endoscopic gastrostomy (PEG) for albumin and visceral protein replenishment. The first patient was a 53-year-old woman (body mass index [BMI], 85.8; weight, 191kg) who presented with respiratory distress and dysphagia; the second was a 26-year-old woman (BMI, 88.6; weight, 259kg) who presented ...
