Study Objective:
To study the efficacy of the transversus abdominal plane (TAP) block.
Design:
Meta-analysis.
Setting:
District general hospital.
Patients:
86 patients in the TAP block group and 88 in the non-TAP block group.
Measurements:
Statistical analyses were performed using Microsoft Excel 2007 for Windows XP. Hedges g statistic was used for the calculation of standardized mean differences (SMD). Binary data (nausea) were summarized as risk ratios (RR).
Main Results:
Patients with TAP block required less morphine after 24 hours than those who did not have the block (random effects model: SMD -4.81, 95% CI [-7.45, -2.17], z = -3.57, P < 0.001). There was less time to first request of morphine in the non-TAP block group (random effects model: SMD 4.80, 95% CI [2.16, 7.43], z = 3.57, P < 0.001). Patients in the TAP block group had less pain up to 24 hours postoperatively. No statistical differences were found with respect to nausea.
Conclusions:
TAP block reduces the need for postoperative opioid use, it increases the time first request for further analgesia, it provides more effective pain relief, and it reduces opioid-associated side effects.

As the drone's propellers rotate, an upward force is generated that counteracts the force of gravity, enabling the drone to lift off from the ground. This initial movement of the drone is along a straight path, representing a form of translational motion. In this phase, every point on the...
