Randomized Controlled Trial
A small dose of remifentanil pretreatment suppresses sufentanil-induced cough during general anesthesia induction: a randomized, double-blind, placebo-controlled trial.
Intravenous use of sufentanil can elicit cough. This study aimed to evaluate the inhibitory effect of pre-injection of a mall dose of remifentanil on sufentanil-induced cough during the induction of general anesthesia. ⋯ Pretreatment with a small dose of remifentanil effectively and safely reduced the incidence and severity of cough induced by sufentanil during anesthesia induction and can be used as an alternative treatment to inhibit coughing caused by sufentanil.

Randomized Controlled Trial
Lateral femoral cutaneous nerve block with different volumes of Ropivacaine: a randomized trial in healthy volunteers.
Nerve block of the lateral femoral cutaneous nerve (LFCN) is a predominantly sensory block. It reduces pain following total hip arthroplasty (THA), but the non-responder rate is high. We hypothesized, that an increased volume of ropivacaine, would result in greater coverage of incisions used for THA. ⋯ A LFCN-block with increased volume of ropivacaine from 8 mL to 16 mL did not result in a greater coverage of posterior or lateral incision lines used for THA, but in a larger blocked sensory area.

Randomized Controlled Trial Comparative Study
A comparison between the Disposcope endoscope and fibreoptic bronchoscope for nasotracheal intubation: a randomized controlled trial.
Nasotracheal intubation (NTI) is frequently performed for oral and maxillofacial surgeries. This study evaluated whether NTI is easier when guided by Disposcope endoscopy or fibreoptic bronchoscopy. ⋯ NTI can be completed successfully using either fibreoptic bronchoscopy or Disposcope endoscope as a guide without any severe complications. However, compared to fibreoptic bronchoscopy, Disposcope endoscope requires less execution time (the NTI time).

Randomized Controlled Trial
Impact of brief prewarming on anesthesia-related core-temperature drop, hemodynamics, microperfusion and postoperative ventilation in cytoreductive surgery of ovarian cancer: a randomized trial.
General (GA)- and epidural-anesthesia may cause a drop in body-core-temperature (BCTdrop), and hypothermia, which may alter tissue oxygenation (StO2) and microperfusion after cytoreductive surgery for ovarian cancer. Cell metabolism of subcutaneous fat- or skeletal muscle cells, measured in microdialysis, may be affected. We hypothesized that forced-air prewarming during epidural catheter placement and induction of GA maintains normothermia and improves microperfusion. ⋯ Prewarming at 43 °C reduces the BCTdrop and maintains normothermia without impeding the perioperative routine patient flow. Microdialysis indicate better preserved parameters of microperfusion.

Postoperative pulmonary complications (PPCs) represent the most frequent complications after esophagectomy. The aim of this study was to identify modifiable risk factors for PPCs and 90-days mortality related to PPCs after esophagectomy in esophageal cancer patients. ⋯ In esophageal cancer patients undergoing esophagectomy via thoracotomy, epidural analgesia and the avoidance of intraoperative blood transfusion are significantly associated with a reduced 90-days mortality related to PPCs.
