Hospital acquired gram-negative pneumonias: response rate and dosage requirements with individualized tobramycin therapy.

abstract：BACKGROUND:Previous reports have suggested that polymorphism of the opioid receptor A118G affects the efficacy of opioid analgesia. The aim of this study was to investigate whether such polymorphism contributed to variability in epidural mixture (sufentanil plus ropivacaine) requirements through patient-controlled epid...
