Clinical Trial Summary

Management of pain after caesarean section represents an important anesthesiologic issue, since it is often suboptimal, leading to delayed functional recovery and chronic pain. Currently, the postoperative analgesic strategy mostly relies on intrathecal morphine (ITM) and multimodal analgesic regimen. Recently, the need for alterative opioid sparing techniques is emerging. Paraspinal fascial plane blocks, as quadratus lumborum block (QLB) and erector spinae plane block (ESPB) performed at T9 level, have therefore been proposed as alternatives to ITM, because of their demonstrated effect on visceral and somatic pain.

The aim of the study is to assess the efficacy, the feasibility and safety of bilateral ESPB compared to bilateral QLB for the management of postoperative pain after ceasarean section conducted under spinal anesthesia without ITM.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Opioid consumption at 24 h	Total morphine consumption at 24 hours from block performance	24 hours from block performance
Secondary	Intensity of pain at time of block performance	NRS (Numeric Rating Scale) for pain at rest and on movement at time of block performance. NRS is an 11-point numeric scale ranging from 0 (= no pain) to 10 (=extreme pain)	Time of block performance, at the end of surgery
Secondary	Intensity of pain at 2 hours	NRS (Numeric Rating Scale) for pain at rest and on movement at 2 hours from block performance. NRS is an 11-point numeric scale ranging from 0 (= no pain) to 10 (=extreme pain)	2 hours from block performance
Secondary	Intensity of pain at 6 hours	NRS (Numeric Rating Scale) for pain at rest and on movement at 6 hours from block performance. NRS is an 11-point numeric scale ranging from 0 (= no pain) to 10 (=extreme pain)	6 hours from block performance
Secondary	Intensity of pain at 12 hours	NRS (Numeric Rating Scale) for pain at rest and on movement at 12 hours from block performance. NRS is an 11-point numeric scale ranging from 0 (= no pain) to 10 (=extreme pain)	12 hours from block performance
Secondary	Intensity of pain at 24 hours	NRS (Numeric Rating Scale) for pain at rest and on movement at 24 hours from block performance. NRS is an 11-point numeric scale ranging from 0 (= no pain) to 10 (=extreme pain)	24 hours from block performance
Secondary	Adverse events	Any adverse events, like sedation, itching, nausea, and other complications, particularly signs of local anesthetic toxicity, the occurrence or persistence of motor weakness at the lower extremities after spinal anesthesia recovery.	Any time during the first 24 hours from block performance.
Secondary	Time to first opioid request	Interval time between block and first opioid analgesic request	Any time during the first 24 hours from block performance
Secondary	Differences in hemodynamic parameters	Any difference in hemodynamic parameters (non-invasive blood pressure, heart rate)	Any time during the first 24 hours from block performance
