Abstract

Intubation is known to cause an exaggerated hemodynamic response in the form of tachycardia, hypertension, and dysrhythmias. In cervical spine instability, intubation has to be performed using cervical immobilization to prevent exacerbation of spinal cord injuries. Application of rigid cervical collar may reduce cervical spine movements, but it hinders tracheal intubation with a standard laryngoscope. The aim of this study was to compare the hemodynamic responses to fiberoptic bronchoscope (FOB) and McCoy laryngoscope in patients undergoing elective surgery under general anesthesia with rigid cervical collar simulating cervical spine immobilization in the situation of cervical trauma. Thirty-two patients in the age range 20-50 years, of American Society of Anaesthesiologist I-II, and of either sex undergoing elective surgery under general anesthesia were randomly allocated into each group. There were two groups according to the technique used for intubation: Group A (flexible FOB) and Group B (McCoy laryngoscope). Systolic blood pressure, diastolic blood pressure, mean arterial blood pressure and heart rate (HR) were recorded at baseline, intraoperatively, immediately before and after induction, and immediately after intubation...Continue Reading

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
