“…According to Morgan,[19] length of oral endotracheal tube (cm) = height of the patient (cm)/10 + 5. Techanivate and coworkers[7] suggested ‘Chula formula’ for determining required length of the endotracheal tube.…”

Background:Malpositioning of endotracheal tube may lead to serious complications like endobronchial intubation or accidental extubation. Using anatomical measurements for prediction of airway length would be more practical in resource constrained settings.Materials and Methods:One hundred adult patients of American Society of Anesthesiologists (ASA) grade 1 or 2, without any evidence of difficult airway, were randomly allocated to two cohorts — a model cohort of 70 (50 males) and test cohort of 30 (20 males) subjects. Height, the straight length from the upper incisor to manubrio-sternal joint in fully extended head position (IncManustL), the length from upper incisor to the carina in neutral head position (IncCarinaL), and degree of neck extension were measured in all subjects. Relationship between the two lengths in the model cohort was explored by Pearson's coefficient (r). Predictions were made for subjects in the test cohort and actual and predicted values assessed for agreement using intra-class correlation coefficient (ICC).Results:Good agreement was found between IncManustL and IncCarinaL for both male (r = 0.69) and female (r = 0.54) subjects. Multiple regression analysis suggested height to be another significant predictor, unlike age, weight, and neck extension. The gender-specific regression equations were used to predict IncCarinaL for the test cohort. ICC for absolute agreement between the actual and predicted values was 0.723 (95% CI 0.495-0.858).Conclusions:It is possible to predict airway length in adult Indian subjects by making two simple anatomical measurements, namely stature and incisor manubrio-sternal joint length.

“…Propofol is a commonly used intravenous drug for sedation in the operating room or intensive care. The green urine color due to propofol is thought to be a result of its phenolic green metabolite produced in the liver and excreted in the urine [2,4]. This green discoloration associated with propofol is benign, non-nephrotoxic, and reversible with drug discontinuation [1,2].…”

“…The green urine color due to Propofol is thought to be a result of its phenolic green metabolite produced in the liver and excreted in the urine. Standard urine analysis and urine cultures remain unremarkable [14][15][16][17]. This drug reaction is dose-dependent and usually appears after a continuous infusion of Propofol.…”

Introduction: Propofol is an intravenous general anesthetic and sedation drug for use in the induction and maintenance of anesthesia or sedation. It is included in WHO Model List of Essential medicines and approved by the FDA (food and drug administration) in 1989. The side effects of Propofol have been studied widely in the last 25 years. They can be easily managed and that is why Propofol has become a first choice drug for the most of the anesthesiologists worldwide. This paper presents a case report of Propofol induced pulmonary edema and also a review of some of the rarest and unusual manifestations of Propofol side effects. Some of them are urine discoloration, tissue necrosis, rhabdomyolysis and postoperative pancreatitis. Methods and materials: A case summary of 18-years old woman with unusual postoperative pulmonary reaction was considered along with other documented cases. Several full-text articles were briefly analyzed for estimating the role of Propofol for a number of strange and potentially life threatening conditions. Results: Despite the low incidence rate, the presented case could be determined as a pulmonary edema due to its clinical features. Furthermore, rare drug reactions such as rhabdomyolysis, tissue necrosis, postoperative pancreatitis etc. may remain unrecognized and create diagnostic and therapeutic issues. Conclusions: Although the officially reported dangerous reaction, Propofol remains one of the best hypnotic and sedative agents. The better knowledge of the full list of drug reactions considered as rare and very rare is a guarantee of an adequate and a better therapeutic behavior.
