Abstract
SUMMARY
mbilical hernia repair, a common day-surgery procedure, is
associated with considerable postoperative discomfort. The
goal of postoperative pain management is provision of comfort,
early mobilization and improved respiratory function without
causing inadequate sedation and respiratory compromise, which
can be achieved through using multimodal analgesic therapy,
preference for regional techniques, avoidance of sedatives, noninvasive
ventilation with supplemental oxygen and early
mobilization.
In the past few years, rectus sheath block has been
increasingly used for postoperative pain relief after paraumbilical
hernia repair surgery. The main advantage of
quadratus lumborum block (QLB) compared to rectus sheath
block is the extension of local anaesthetic agent beyond the
transversus abdominis plane to the thoracic paravertebral space.
The wider spread of the local anaesthetic agents may produce
extensive analgesia and prolonged action of the injected local
anaesthetic solution.
The aim of this study was to assess the analgesic efficacy
of ultrasound-guided posterior QLB compared with rectus
sheath block during para-umbilical hernia repair surgery and in
the early postoperative period regarding pain relief, provision
of comfort, and improved respiratory functions.

Summary

After approval of anaesthesiology department scientific
and ethical committees in Ain Shams University Hospitals,
patients were included in the study, and were divided into two
groups (n=20; each); group QLB and group RSB.
group QLB: Patients (n=20) of this group received
bilateral ultrasound-guided QLB after induction of
general anesthesia using 0.2 ml/kg bupivacaine 0.25%.
group RSB: Patients (n=20) of this group received
bilateral ultrasound-guided rectus sheath block after
induction of general anesthesia using 0.2 ml/kg
bupivacaine 0.25%.
The two groups were adequately monitored and assessed
post-operatively and they were compared regarding analgesic
outcome by using the visual analogue scaling system, besides,
recording time for first call for rescue analgesia. Demographic
data, post-operative hemodynamics, and sedation score were
also assessed.
