[Hemodynamic effects of local anesthetics with adrenaline during septal surgery].

OBJECTIVES

We investigated the hemodynamic effects of local anesthetics with adrenaline used before septal surgery.

PATIENTS AND METHODS

In a prospective, controlled design, administration of local anesthetics was performed with and without adrenaline in 39 patients and 10 patients, respectively, undergoing septal surgery. Plasma adrenaline concentrations were measured before anesthesia, and after 2, 5, and 10 minutes from anesthesia. The patients were monitored with respect to pulse rate, electrocardiographic findings, and blood pressure.

RESULTS

Preoperative plasma adrenaline levels were similar in patients receiving local anesthetics with or without adrenaline (0.8 nmol/l vs 0.7 nmol/l). Following adrenaline administration, adrenaline levels showed significant increases to 2.2, 1.9, and 1.7 nmol/l after 2, 5, and 10 minutes, respectively (p<0.001), whereas they remained similar in the control group. No side effects related to adrenaline use were detected.

CONCLUSION

Despite systemic absorption of local injections, adrenaline-related side effects during septal surgery are extremely rare when the patients are closely monitored.
