We investigated the effects of the PENG block on postoperative opioid consumption after a hip surgery. This was a randomized, double-blind, placebo-controlled study conducted at a single institution. Fifty patients undergoing hip surgery were randomly allocated, 25 in each group, to receive a PENG block either using 25\u2009mL of 0.5% ropivacaine (PENG group) or 25\u2009mL of saline (control group). The primary outcome was the total opioid consumption 24\u2009h postoperatively. The secondary outcomes were postoperative pain scores, time to first opioid demand, sensory block efficiency, quadriceps muscle strength, complications, and patient satisfaction. Compared with those in the control group, patients in the PENG group had a significantly lower total opioid consumption 24\u2009h postoperatively (440.72\u2009\u00b1\u2009242.20\u2009\u03bcg vs. 611.07\u2009\u00b1\u2009313.89\u2009\u03bcg, P\u2009=\u20090.037) and significantly lower pain scores at 30\u2009min postblock and 6 postoperatively (\n                    <jats:inline-formula>\n                      <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mi>P<\/a:mi>\n                        <a:mo>&lt;<\/a:mo>\n                        <a:mn>0.001<\/a:mn>\n                      <\/a:math>\n                    <\/jats:inline-formula>\n                    and\n                    <jats:inline-formula>\n                      <c:math xmlns:c=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\">\n                        <c:mi>P<\/c:mi>\n                        <c:mo>&lt;<\/c:mo>\n                        <c:mn>0.001<\/c:mn>\n                      <\/c:math>\n                    <\/jats:inline-formula>\n                    , respectively).

Sensory block effectiveness was better in the PENG group 30\u2009min postblock and 6 and 12\u2009h postoperatively than in the control group. Patient satisfaction was also better in the PENG group than in the control group. There were no differences in the other outcomes. The PENG block reduced the total opioid consumption in the first 24\u2009h after hip surgery with no significant effects on quadriceps muscle strength and complication rate.
