Randomized Controlled Trial
Effects of continuous and slow tracheal tube cuff deflation on cough reflex during extubation in noncardiac surgery patients: a randomised clinical trial.
The incidence of cough reflex during extubation is 76%. Cough reflex causes severe hemodynamic fluctuations and airway complications. This prospective trial investigated the potential effects of tracheal tube cuff deflation on cough reflex during extubation. ⋯ Compared with deflating a trachal tube cuff with a 10-ml syringe in 1 s, the use of a 10-ml syringe at a speed of 1 ml s-1 or a cuff pressure guage within 5 s can both reduce the incidence of cough reflex, but deflating with a cuff pressure guage can increase the incidence of postoperative hoarseness.

In civilian life, from 11 to 40% of patients suffer from chronic pain after receiving injuries. There are almost no data on chronic pain in patients with gunshot wounds, isolated clinical cases have been published. The purpose of our study is to determine the factors that can potentially affect the results of treatment of such patients, namely the frequency of development of chronic pain, acute stress reactions, satisfaction with the results of treatment and the number of wound localizations. ⋯ Patients with gunshot wounds have a high risk of chronic pain, averaging 45% higher than the general population in civilian trauma patients. A greater frequency of the neuropathic component of pain and acute stress reactions is the reason for such chronicity. A decrease in the level of satisfaction with the results of treatment, in the remote period of observation, compared to the level at the time of discharge from the hospital, is probably a consequence of the formation of chronic pain.

Randomized Controlled Trial
There is no evidence that carbon dioxide-enriched oxygen before apnea affects the time to arterial desaturation, but it might improve cerebral oxygenation in anesthetized obese patients: a single-blinded randomized crossover trial.
Carbon dioxide (CO2) increases cerebral perfusion. The effect of CO2 on apnea tolerance, such as after anesthesia induction, is unknown. This study aimed to assess if cerebral apnea tolerance can be improved in obese patients under general anesthesia when comparing O2/Air (95%O2) to O2/CO2 (95%O2/5%CO2). ⋯ O2/CO2 improves cerebral TOI and PaO2 in anesthetized bariatric patients. Better apnea tolerance could not be confirmed.

Randomized Controlled Trial
Comparison of analgesic efficacy of different local anesthetic volumes for erector spinae plane block in thoracotomy patients; a prospective randomized trial.
Erector spinae plane block (ESPB) is a thoracic wall block that has been used frequently in recent years. It was aimed to compare the analgesic efficacy of bupivacaine in different volumes for ESPB in patients undergoing thoracotomy. ⋯ The results of ESPB applied with 20 ml and 30 ml of local anesthetic before the surgical incision in thoracotomy patients showed that the use of 30 ml of local anesthetic provided more effective analgesia. In addition, similar side-effect rates show that 30 ml of local anesthetic can be used safely.
