Abstract


The  study  was conducted  on  60  children  and  adults  admitted  for  tonsillectomy  to  compare  the  efficacy  of  lignocaine
spray and infiltration for post-tonsillectomy analgesia. They were divided into three groups equally i.e. 20 cases in
each group, where Group A included  those patients who did not receive  spray of 4% lignocaine  or infiltration of 1%
lignocaine  at the end of surgery .  Group B included  those patients who were treated with 4% lignocaine  spray at the
end of surgery .  Lastly ,  Group C included  those  patients  who were treated with injection  of 1% lignocaine  infiltration
at  the  end of surgery .  The mean time  required for onset of pain was 0.79 hours  in  group A and 3.94 hours  in  group B,
and 3.79 hours in group C patients which showed superiority of the treatment given to group B and C patients for
post-operative  analgesia.  Also,  the  t-value  was found  significant  with p<0.001. Thus,it  is  statistically  proven  that
spray  of  4%  lignocaine  and  1%  lignocaine  infiltration  helps  to  delay  the  onset  of  pain  after  surgery .
Patients were assessed for postoperative duration of analgesia induced by lignocaine  treatment in study groups. It
can be concluded that the spray of 4% lignocaine  or infiltration of 1% lignocaine  at the site of operation before the
patient  recover  from  anesthesia,  postpones  the  need  for  parenteral  administration  of  narcotic  analgesics.  This
allows safe recovery from anaesthesia without pain, avoiding the side effects of general anaesthesia and narcotic
analgesia.
