Randomized Controlled Trial
Randomized prospective study of olecranon fracture fixation: cable pin system versus tension band wiring.
This prospective, randomized study compared the effectiveness of the cable pin system (CPS) versus tension band wiring (TBW) for olecranon fracture fixation. ⋯ Internal fixation by CPS is an effective method for olecranon fracture and is associated with a shorter healing time, fewer complications and better function than TBW.

Randomized Controlled Trial
Effects of preoperative gabapentin on postoperative pain after radical retropubic prostatectomy.
The impact of preoperative gabapentin on tramadol consumption using patient-controlled analgesia (PCA) and postoperative pain was assessed in patients undergoing radical retropubic prostatectomy (RRP). ⋯ Preoperative administration of 900 mg gabapentin did not decrease tramadol consumption, but was associated with lower pain scores in the early postoperative phase and a reduced need for rescue analgesia, compared with controls, in patients undergoing RRP.

Randomized Controlled Trial
Selective neurogenic blockade and perioperative immune reactivity in patients undergoing lung resection.
This double-blind, prospective, randomized, controlled trial examined the effects of thoracic epidural block and intravenous clonidine and opioid treatment on the postoperative Th1/Th2 cytokine ratio after lung surgery. The primary endpoint was the interferon γ (IFN-γ; Th1 cytokine)/interleukin 4 (IL-4; Th2 cytokine) ratio. Secondary endpoints were reductions in pain and incidence of pneumonia. ⋯ Intraoperative thoracic epidural block decreased the IFN-γ/IL-4 ratio immediately after lung surgery, indicating less inflammatory stimulation during surgery.

Change in thoracic fluid content (TFC) derived via a bioreactance technique with a noninvasive cardiac output monitoring device (NICOM) reportedly shows a good correlation with the amount of fluid removed. The present study prospectively evaluated the utility and clinical application of TFC in the intraoperative fluid management of paediatric patients with congenital heart disease, undergoing cardiac surgery with bioreactance-based noninvasive monitoring. ⋯ TFCd0% may be a useful indicator for intraoperative fluid management in paediatric patients with congenital heart disease, undergoing cardiac surgery.

The characteristics of sleep apnoea syndrome (SAS) in the elderly, including subtype classification and association with mortality, have not been fully elucidated. This study examined these factors in an elderly Japanese inpatient population. ⋯ Obstructive, central and mixed SAS were associated with increased risk of cardiovascular related and all-cause mortality. Mixed SAS was associated with an increase in mortality from pneumonia. There was no relationship between mortality and severity of SAS.
