Randomized Controlled Trial
Evaluation of hemodynamic goal-directed therapy to reduce the incidence of bone cement implantation syndrome in patients undergoing cemented hip arthroplasty - a randomized parallel-arm trial.
The bone cement implantation syndrome (BCIS) is a frequent and potentially disastrous intraoperative complication in patients undergoing cemented hip arthroplasty. Several risk factors have been identified, however randomized controlled trials to reduce the incidence of BCIS are still pending. We hypothesized that goal-directed hemodynamic therapy guided by esophageal Doppler monitoring (EDM) may reduce the incidence of BCIS in a randomized, controlled parallel-arm trial. ⋯ The implementation of a specific hemodynamic goal-directed therapy did not reduce the overall incidence of BCIS in patients undergoing cemented hip arthroplasty.

Contribution of the small intestine to systemic inflammation after cardiac arrest (CA) is poorly understood. The objective was to evaluate whether an in vivo rat model of 6 min CA is suitable to initiate intestinal ischaemia-reperfusion-injury and to evaluate histomorphological changes and inflammatory processes in the small intestinal mucosa resp. in sera. ⋯ CA resulted in mild small intestinal tissue damage but not in systemic inflammation. A rat model of 6 min CA is not capable to comprehensively mimic a post cardiac arrest syndrome (PCAS). Whether there is a vital influence of the intestine on the PCAS still remains unclear.

Case Reports
Entrapment of a laryngotracheal topical anesthesia kit during tracheobronchial foreign body removal: a case report.
In order to reduce the irritation of the airway during tracheobronchial foreign body (TFB) removal, tracheal surface anesthesia is usually performed using a laryngotracheal topical anesthesia (LTA) kit (LTA20, Highgreen Medical Technology Company, China), but difficulty in withdrawing the LTA kit is rarely reported. We present a case of a difficulty to withdraw the LTA kit due to its entrapment by the movement of a TFB. ⋯ This case report draws our attention to a significant anesthetic clinical consideration during the application of topical anesthesia on the trachea for TFB removal. The possibility of coughing or bucking can lead to migration of the TFB with subsequent airway obstruction, so the depth of anesthesia must be sufficient to prevent harmful reflexes. Also, strong teamwork and good communication are paramount to avoid serious complications.

Arytenoid dislocation (AD) is a rare but severe complication after general anesthesia with endotracheal intubation. We conducted a case-control study at Peking Union Medical College Hospital to identify risk factors associated with AD, including the use of an intubation stylet. ⋯ The use of an intubation stylet for endotracheal intubation appears to protect against AD. Prolonged operation time increases the risk of AD. These factors should be considered when assessing the risks of AD associated with endotracheal intubation and in efforts to avoid this complication.
