Summary: | Introduction: Intrathecal opioids when added to local
anaesthetics decrease their dosage and provide haemodynamic
stability. Nalbuphine is an agonist-antagonist and acts on kappa
receptors providing analgesia.
Aim: The study aims to compare the analgesic efficacy of
fentanyl with that of two doses of nalbuphine when used with
injection bupivacaine heavy in spinal anaesthesia.
Materials and Methods: A randomised, double blinded,
prospective study on 90 patients of ASA I and II undergoing
lower limb orthopaedic surgery under subarachnoid block
was done. Patients were randomly allocated into three groups
(n=30). Each group received 12.5 mg of 0.5% of injection
bupivacaine heavy along with either 25 µg of 0.5 ml fentanyl
(Group F) or 0.8 mg of 0.5 ml nalbuphine (Group NL) or 1.6 mg
of 0.5 ml nalbuphine (Group NH). Characteristics of sensory
and motor blocks, haemodynamic changes, duration and
quality of analgesia, adverse effects, sedation, VRS score and
analgesic requirement were studied at different time interval
intraoperatively and till 24 hours of block.
Results: The duration of analgesia (in minute) was 441±119.69
in NL Group, 450±103.38 in NH Group and 300.0±88.53 in
Group F (p=0.05). There was no significant difference regarding
block characteristics and haemodynamic parameters. Total 24
hours analgesic requirement was titrated by analgesic score
which was 2.25±0.7 (NH Group), 1.875±0.83 (NL Group) and
3.375±1.77 (F Group) p=0.0186 by ANOVA. The adverse effects
of NL Group were least.
Conclusion: There was no significant advantage of intrathecal
fentanyl or 1.6 mg nalbuphine over low dose 0.8 mg
nalbuphine. |
