| description | Cardiovascular responses include increase in blood pressure and heart
rate is a common event after laryngoscopy and tracheal intubation, and it
has potentially adverse side effects especially in high risk patients. The cause
of cardiovascular responses is stimulation of receptors in autonomic nervous
system with plasma increase in noradrenalin and other catecholamines.
Sometimes this response is in from of parasympathic and vagus nerve
stimulation and lead to bradycardia especially in children . The purpose of
this study is comparison and survey of lidocaine and fentanyl effects on
prevention or attenuating cardiovascular responses after laryngoscopy
and tracheal intubation in patients who referred to Hamadan hospitals for
elective surgery in 1998.
We studied a total of 96 patients , ASA class I and II received a
balanced anesthesia were randomly divided into three groups. In the
induction of anesthesia and before laryngoscopy and tracheal intubation,
group 1 received saline 5 ml , group 2 received lidocaine 1.5 mg/kg and
group 3 received fentanyl 2 g/kg. Patients and investigator was blinded
to it.Blood pressure and heart rate were recorded at following times:before
induction , after induction but before laryngoscopy and intubation , and
1,3,5 minutes after intubation.Then the mean of hemodynamic parameters
in steps one and two compared with the same parameters in three
following steps.
Fentanyl effectively blunted the hemodynamic responses to
laryngoscopy and tracheal intubation but saline and lidocaine were found
to be ineffective in abolish or attenuating these same response.
So according to this study fentanyl is more useful adjunct for preventing
hemodynamic responses after laryngoscopy and tracheal intubation than
lidocaine. |
