Randomized Controlled TrialPropofol reduces early post-operative pain after gynecological laparoscopy.
There is some evidence that propofol may reduce post-operative pain. However, the results on the analgesic effects of propofol are inconsistent. Thus, we hypothesized that propofol reduces acute pain if confounding factors like opioids are avoided. ⋯ Propofol anesthesia was associated with significantly less pain at 0.5 and 1 h after surgery in patients undergoing gynecological laparoscopies with planned opioid-free post-operative analgesia.

Randomized Controlled TrialEffects of intravenous dexmedetomidine on low-dose bupivacaine spinal anaesthesia in elderly patients.
Dexmedetomidine (DMT) has been shown to prolong spinal anaesthesia. We evaluated the effects of intravenous DMT on low-dose bupivacaine spinal anaesthesia in elderly patients. ⋯ Intravenous DMT prolonged the duration of spinal anaesthesia and improved post-operative analgesia. However, more profound sedation with desaturation was observed with more frequent bradycardia, and delayed recovery should be considered in elderly patients.

The implementation of a perioperative checklist increases patients' perioperative safety and staff satisfaction.
The implementation of the 'Surgical Safety Checklist' caused a significant reduction in the incidence of complications and mortality among patients undergoing surgery. The aim of the present study was to evaluate perioperative safety standards and the quality of interprofessional cooperation before and after the introduction of a safety checklist from staff members' point of view. ⋯ Our attitude surveys demonstrate that from the OR staff's perspective, in the perioperative setting, safety-relevant factors can be handled significantly better and with greater awareness by implementing a safety checklist as proposed by the World Health Organization.

Central venous oxygen saturation is a good indicator of altered oxygen balance in isovolemic anemia.
Red blood cell transfusion is done primarily as a means to improve oxygen delivery (DO₂). Current transfusion guidelines are based solely on hemoglobin levels, regardless of actual DO₂ need. As central venous oxygen saturation (ScvO₂) may reflect imbalances in DO₂ and consumption (VO₂) the aim of this study was to investigate the value of ScvO₂ as an indicator of oxygen balance in isovolemic anemia. ⋯ The results of this study show that ScvO₂ reflects changes of VO₂/DO₂ in isovolemic anemia better than Hb alone, therefore it may be used as an additional indicator of blood transfusion in clinical practice.

Randomized Controlled TrialEffects of adductor-canal-blockade on pain and ambulation after total knee arthroplasty: a randomized study.
Total knee arthroplasty (TKA) is associated with intense post-operative pain. Besides providing optimal analgesia, reduction in side effects and enhanced mobilization are important in this elderly population. The adductor-canal-blockade is theoretically an almost pure sensory blockade. We hypothesized that the adductor-canal-blockade may reduce morphine consumption (primary endpoint), improve pain relief, enhance early ambulation ability, and reduce side effects (secondary endpoints) after TKA compared with placebo. ⋯ The adductor-canal-blockade significantly reduced morphine consumption and pain during 45 degrees flexion of the knee compared with placebo. In addition, the adductor-canal-blockade significantly enhanced ambulation ability assessed by the TUG test.
