Quadratus Lumborum Block in Pediatric Patients

Quadratus lumborum block (QLB) is a newly-defined trunk block performed with local anesthetic injection by imaging the abdominal muscles with ultrasonography (US) guidance; thus, analgesia is expected to be ensured from the T7-L1 dermatomal segment level.

In the study, the aim was to compare the postoperative analgesic effect of quadratus lumborum block in pediatric patients undergoing lower abdominal surgery

About this study

Patients included in the study were randomly divided into 2 groups. Cases were assessed as intravenous opioid with 1 mg/kg tramadol HCl (Group O, n=20) or ultrasonography-guided quadratus lumborum block (Group B, n=20).

Total analgesic amounts in 24 hours and first analgesic requirement times recorded.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • The study included 40 cases undergoing lower abdominal surgery aged from 3 to 16 years with ASA (American Society of Anesthesiologist) I-II level.

Exclusion criteria

  • Cases with ASA III-IV health level and those with a history of allergy to local anesthetic medications were not included in the study.

Treatment and study plan

Tramadol Hydrochloride

Drug

The Wong-Baker facial pain scale was used to assess pain (1: no pain, 10: worst possible pain). During monitoring patients with pain score ≥3 had intravenous 1 mg/kg tramadol hydrochloride administered, After 15 minutes following tramadol injection, cases with pain score continuing ≥3 were to be assessed as insufficient analgesia and had 0.1 mg/kg morphine hydrochloride planned for intravenous administration.

Morphine sulfate

Drug

The Wong-Baker facial pain scale was used to assess pain (1: no pain, 10: worst possible pain). During monitoring patients with pain score ≥3 had intravenous 1 mg/kg tramadol hydrochloride administered, After 15 minutes following tramadol injection, cases with pain score continuing ≥3 were to be assessed as insufficient analgesia and had 0.1 mg/kg morphine hydrochloride planned for intravenous administration.
