Randomized Controlled Trial
[Hemodynamic effect of local infiltrative 2% lidocaine adrenaline anesthesia in general balanced anesthesia during middle ear surgery].
Hemodynamic effect of different techniques and type of anesthesia are defined. The volume of reduced hemorrhage in surgical field is debatable, without any definite conclusion. The objective of the study is to investigate the effects of local infiltrative anesthesia with adrenaline during general balanced anesthesia and nitroglicerol on blood presure and hemorrhage reduction in middle ear operations. ⋯ Blood pressure and heart rate was not different between the two groups. But, intraoperatively, the study showed lowering of sistolic and diastolic blood pressure. This mode of treatment and surgeon's verbal reply confirmed that local infiltrative anesthesia with adrenaline under balanced anesthesia had no effect on hemorrhage reductionin surgical field.
