Comparative Study
Severe pulmonary hypertension during pregnancy: mode of delivery and anesthetic management of 15 consecutive cases.
Available literature on pregnant women with severe pulmonary hypertension (PH) relies mainly on anecdotal case reports and two series only. ⋯ Despite the most modern treatment efforts, the maternal mortality was 36%. Scheduled cesarean delivery during combined spinal-epidural anesthesia seemed to be an attractive approach, but there was no evidence of actual benefit. Therefore, pregnancy must still be discouraged in patients with severe PH.

Comparative Study
Painful nerve injury decreases resting cytosolic calcium concentrations in sensory neurons of rats.
Neuropathic pain is difficult to treat and poorly understood at the cellular level. Although cytoplasmic calcium ([Ca]c) critically regulates neuronal function, the effects of peripheral nerve injury on resting sensory neuronal [Ca]c are unknown. ⋯ Painful SNL nerve injury depresses resting [Ca]c in sensory neurons. This is most marked in axotomized neurons, especially the large and capsaicin-insensitive neurons presumed to transmit non-nociceptive sensory information.

Randomized Controlled Trial Comparative Study Clinical Trial
Median effective dose (ED50) of nefopam and ketoprofen in postoperative patients: a study of interaction using sequential analysis and isobolographic analysis.
The analgesic efficacy of ketoprofen has been shown after moderate- and severe-pain surgery, and the analgesic efficacy of nefopam has been shown after moderate-pain surgery. The aim of this study was to define the median effective analgesic doses of each drug and to determine whether the interaction of nefopam and of ketoprofen is synergistic. ⋯ The isobolographic analysis demonstrated that the combination of the two drugs produces effective analgesia with an important synergistic interaction.

Randomized Controlled Trial Comparative Study Clinical Trial
Effect of postoperative epidural analgesia on rehabilitation and pain after hip fracture surgery: a randomized, double-blind, placebo-controlled trial.
Hip fracture surgery usually carries a high demand for rehabilitation and a significant risk of perioperative morbidity and mortality. Postoperative epidural analgesia may reduce morbidity and has been shown to facilitate rehabilitation in elective orthopedic procedures. No studies exist on the effect of postoperative epidural analgesia on pain and rehabilitation after hip fracture surgery. ⋯ Postoperative epidural analgesia after hip fracture surgery provides superior analgesia attenuating pain as a restricting factor during rehabilitation without motor dysfunction. However, superior analgesia did not translate into enhanced rehabilitation. Future studies with multimodal rehabilitation are required to establish whether superior analgesia can be translated into enhanced rehabilitation and reduced morbidity in hip fracture patients.
