Objective: To  determine the efficacy  of  5%  lignocaine  ointment  in  reducing  the  post-operative  pain  following  nasal surgery  with  bilateral  intra - nasal  packs.

Study Design: Randomized,   Prospective, Control study.

Place and Duration of Study: This study was conducted at the ENT Department, Benazir Bhutto Shaheed Teaching  Hospital Abbottabad  from  July 2011  to  June  2012.  

Patients  and  Methods: A total  of  120  patients ,  who  underwent  Septoplasty  were   included  in  the  study

.Patients  were  separated  into  Group A  (n- 40 ), these  patients  were  having  intranasal  packs  soaked  with 

Liquid  paraffin. Group B (n- 40 ), these  patients  were  packed  with  5%  lignocaine  ointment ,and  Group  C, (n 40 ),in  this  one  side  of  the nasal  cavity  was  packed  with  liquid  paraffin (C1)  and  the  other  side  with  5 % lignocaine  ointment (C2) .In  all  three  groups  the  intranasal  packs  were  removed  after  24  hrs. The  severity  of  post operative  pain  and  the  amount  of  analgesics  required  by  each  group  calculated.

Results :  In  group  B  ( n- 40 )  the mean  VAS  was  5.60+-2.40 as  compared  to 7.27+-1.881  in group  A  and  7.40+-1.033 (C1 ), 6.62+-1.764( C2).in   group  C  at  6hrs  post  operatively. The  mean  VAS  at  24  hrs  post operatively  in  group B   was 6.63+-1.125, significantly  lower  than  group  A (7.15+-1.252 )    and  group  C1 (6.07+-1.023).,C2( 4.90+-1.236).

The mean  time  to first  request  for  rescue  analgesia  was   significantly  prolonged  in  group B, 220.53+-42.12 min as  compared  to 148.32+-32.45 min.(group A ) , and 190.61+-35.45 min. (group C). The  total  analgesia (Diclo fenac sodium)  required  post-operatively  was 175.32+-14.13mg in group B , as compared  to 225.14+-25.73mg (group A)  and  200.16+-41.89mg (group C).
