Randomized Controlled Trial Comparative Study
Comparison of intravenous morphine, epidural morphine with/without bupivacaine or ropivacaine in postthoracotomy pain management with patient controlled analgesia technique.
The aim of this randomized, double-blinded, prospective study was to determine the effectiveness and side effects of intravenous or epidural use of morphine, bupivacaine or ropivacaine on post-thoracotomy pain management. ⋯ Morphine used at the epidural route was found more effective than the intravenous route. While Group EM was more effective in the late period of postoperative, Group EMB was more effective in the early period. We concluded that epidural morphine was the most effective and preferred one.

Randomized Controlled Trial
Assessment of the effect of ketamine in combination with remifentanil on postoperative pain.
The combination of ketamine and remifentanil seems to be associated with better analgesia and duration. The aim of this study was to evaluate whether a ketamine-remifentanil combination promotes improved postoperative analgesia. ⋯ The combination of ketamine (5 mcg.kg(-1).min(-1)) and remifentanil (0.4mcg.kg(-1).min(-1)) for cholecystectomy did not alter the severity of postoperative pain, time to first analgesic supplementation or dose of morphine in 24hours.

Randomized Controlled Trial
The effect of levobupivacaine and bupivacaine on QT, corrected QT (Qtc), and P wave dispersions in cesarean section.
In our study we aimed to investigate the effect of bupivacaine and levobupivacaine on QT, corrected QT (QTc), and P wave dispersion durations during spinal anesthesia in cesarean section. ⋯ Sixty parturients scheduled for elective cesarean section in ASA I-II risk groups were included in the study. Baseline electrocardiographic (ECG) records of the patients were obtained in the operation room. Heart rate (HR), non-invasive blood pressure (NIBP), peripheral oxygen saturation (SpO2) and respiration rates (RR) were recorded. Venous cannulation was performed with 18G cannula and fl uid preload made with 10mL.kg(-1). Lactated Ringer solution. After fl uid preload, second ECG recordings were taken and the patients were randomly separated into two groups. Group B (n=30) received 10mg of bupivacaine and Group L (n=30) received 10mg of levobupivacaine for spinal anesthesia. ECG recordings were repeated at 1, 5 and 10minutes after spinal block. HR, NIBP, SpO2 , RR and sensory block levels were also recorded at the same time intervals. At predetermined time intervals of spinal anesthesia, P wave dispersion (Pwd), QT dispersion (QTd), and QTc dispersion (QTcd) durations were measured from ECG records. QT and QTc durations are calculated with Bazzett formula.

Randomized Controlled Trial
The effect of head rotation on intraocular pressure in prone position: a randomized trial.
The increased intraocular pressure (IOP) - which decreases perfusion pressure on the optic nerve - increases by prone positioning (1). The aim of our study was to compare the effect of head rotation 45° laterally in prone position on the increase in IOP of upper placed and lower placed eyes in patients undergoing percutaneous nephrolithotomy (PCNL). ⋯ prone positioning increases IOP. In patients with prone position with a head rotation of 45° laterally, IOP in the upper positioned eye was significantly lower.
