Cardiomyopathies and anaesthesia.

Cardiomyopathy is considered as a heart muscle disease of multiple aetiologies, unlike other cardiac diseases related to a definitive pathophysiology. With more and more research and with the advent of genetic analysis pin pointing the disease causing mutations, causative factors have been defined and classifications and definitions have changed over time. Patients with these conditions present to anaesthesiologists in elective and emergency situations, placement of automated internal cardioverter defibrillator (AICD) devices or biventricular pacing but may also be diagnosed at anaesthetic pre-assessment.

Comparison of different doses of intranasal nitroglycerine in attenuation of pressor response to laryngoscopy and intubation.

Aims: To observe the various pressor responses to laryngoscopy and intubation in normotensive patient undergoing elective surgery under general anesthesia and use of three different attenuating doses (400, 800, 1200 mcg) of intranasal nitroglycerine administered five minutes before laryngoscopy and intubation, to observe the efficacy and safety.

Settings And Design: Randomized study.

Materials And Methods: The study was carried out in a total of 60 patients.
