High-Frequency Transcutaneous Electrical Nerve Stimulation Attenuates Postsurgical Pain and Inhibits Excess Substance P in Rat Dorsal Root Ganglion.
Transcutaneous electrical nerve stimulation (TENS) is a common therapeutic modality for pain management, but its effectiveness in skin/muscle incision and retraction (SMIR)-evoked pain is unknown. We aimed to examine the effects of TENS on postoperative pain and the levels of substance P (SP), N-methyl-D-aspartate receptor 1 (NR1), and interleukin 1β (IL-1β) in rat dorsal root ganglion (DRG). ⋯ Our data demonstrated that TENS intervention reduced persistent postoperative pain caused by SMIR operation. Up-regulation of NR1, SP, and IL-1β in DRG, activated after SMIR surgery, is important in the development of prolonged postincisional pain. The TENS pain relief may be related to the suppression of NR1, SP, and IL-1β in DRG of SMIR rats.

Randomized Controlled Trial Comparative StudyPatient-controlled analgesia after coronary bypass: Remifentanil or sufentanil?
adequate pain control after cardiac surgery is mandatory to reduce its remarkable morbidity. In this study, we aimed to compare the efficacy of patient-controlled analgesia with remifentanil or sufentanil for pain management after coronary artery bypass grafting. ⋯ our study showed that both remifentanil and sufentanil patient-controlled analgesia can provide acceptable analgesia after coronary artery bypass. The difference between their efficacies was inconspicuous until 24 h postoperatively. Remifentanil seems to result in better pain relief at 24 h postoperatively.

Review[Subsyndromal delirium - Experiences from the psychiatry - expectations for postoperative management].
The phenomenon of delirium is well known since over 100 years. The anesthesiology has recognized that early detection and therapy results in significant improvement of postoperative clinical state of health of the patients. In the following article it will be discussed that it could be profitable to make a further step: threatening the subsyndromal delirium. Because there are only few experiences in anesthesiology, this thesis will be substantiated by datas from psychiatry.

The effect of patient sex on the incidence of early adverse effects in a population of elderly patients.
Patient sex is known to influence the response to general and regional anaesthesia and recovery after surgery. However, most studies come from analyses carried out on middle-aged patients. As most of the patients admitted to the post-anaesthesia recovery room in our institution are elderly, we took the opportunity to investigate the association between sex and incidence of early adverse events in this older population of patients after major surgery. ⋯ Women showed a higher incidence of shivering (relative difference +48%, P=0.0003), postoperative nausea and vomiting (+91%, P<0.0001), hypotension (+32%, P=0.044) and desaturation (+60%, P=0.0030) than men. The incidence of hypertensive response, arrhythmias and acute respiratory failure were not statistically significantly different. The findings of this exploratory study suggest that women have a higher risk of early postoperative adverse events even in a more elderly population.

Comparative Study Observational StudySerum high-mobility group box 1 protein correlates with cognitive decline after gastrointestinal surgery.
Accumulating evidence has indicated that inflammation may act as a potential mechanism underlying post-operative cognitive dysfunction (POCD). High-mobility group box 1 (HMGB1), as a known late mediator of inflammation, is involved in the development of post-operative complications. Thus, we sought to determine the role of HMGB1 in reflecting POCD following major gastrointestinal surgery. ⋯ Serum HMGB1 and IL-6 levels increase significantly after major gastrointestinal surgery in elderly patients and such elevations are associated with the occurrence of cognitive decline after surgery.
