Implication
Epidural opiates may not alleviate surgery-induced diaphragmatic dysfunction; this case report leaves open the need for prospective trials.
Structured PICO
Does opiate epidural analgesia improve diaphragmatic dysfunction induced by upper abdominal surgery?
P
Population
5 patients undergoing upper abdominal surgery
I
Intervention
Opiate epidural analgesia administered on the first postoperative day
C
Comparator
Baseline (pre-operative) values
O
Outcome
Diaphragmatic function parameters (Vab/Vt, delta Pab/delta Pdi, Pdimax, cephalocaudal diaphragmatic displacement)surrogate
Upper abdominal surgery induces marked diaphragmatic dysfunction lasting about 1 week that is not reversed by postoperative pain relief with epidural opiates.
