RESUMO
OBJECTIVES: This study aimed to evaluate the effect of serratus anterior plane block (SAP) on postoperative morphine consumption. We aimed to determine the differences between both similar blocks and evaluate the effect of the methods of application of this block on patients' postoperative pain scores and morphine consumption. MATERIAL AND METHODS: This study is a single-center, prospective and observational study performed with 40 volunteer patients with American Society of Anesthesiologists (ASA) I-III, who were 18-70 years of age, scheduled for breast surgery. A total of 40 patients who underwent general anesthesia were divided into two groups each with 20 patients. While SAP block was applied to the study group, no block was applied to the control group. SAP block was made by injecting a total of 40 ml of 0.25% bupivacaine between 2 muscles after the test dose was injected with saline. All patients were followed up for 12 hours postoperatively with patient-controlled analgesia (PCA) pump. Morphine consumption, visual analogue score (VAS) values and side effects were recorded at the postoperative 1st, 6th and 12th hours. RESULTS: There was no significant difference between the two groups in terms of hemodynamic parameters and demographic data. Postoperative morphine consumption and postoperative analgesic requirement were significantly lower in the SAP block group (p <0.001). Postoperative VAS values were significantly lower in the SAP block group (p <0.001). No complication was observed related to the block. CONCLUSION: It was found that the SAP block reduced morphine consumption, significantly decreased VAS values, and reduced side effects due to opioids postoperatively.
RESUMO
Vertebral artery cannulation is an unusual complication during internal jugular vein cannulation. We report a case of vertebral artery cannulation, which occurred during an attempt to cannulate the right internal jugular vein, and we discuss the management of such a rare complication.

OBJECTIVE: The aim of the present study was to compare the effects of two inhalation anesthetics, desflurane and sevoflurane, on middle ear pressure. METHODS: After we obtained written consent from the patients and the approval from our institutional ethical committee, we included 56 ASA I-II patients aged between 18 and 60 years in this study. They were randomly divided into two groups of 28 patients each. Desflurane 4-6% (Group D) or sevoflurane 1-2% (Group S) were used for anesthesia management in patients. Baseline tympanometry was carried out and recorded before the induction of anesthesia on both ears, and 3 more measurements were done and recorded 5, 15 and 30 min after induction. RESULTS: In both groups, middle ear pressure values were found to be significantly elevated when compared to baseline measurements (p < 0.05). When middle ear pressure was compared between the groups, no difference was found between the values obtained at baseline and at 5 min in Group S, while especially the values obtained at 15 min revealed significantly higher middle ear pressures in Group D. CONCLUSION: It was observed that the increase in middle ear pressure caused by sevoflurane was significantly lower than that caused by desflurane.

OBJECTIVE: In this study we aimed to compare the echogenic needles and the nerve stimulation addition to non-echogenic needles in ultrasound guided axillary brachial plexus block for upper extremity surgery. METHODS: 90 patients were enrolled to the study. The patients were allocated into three groups randomly: Group E (n=30): ultrasound guided axillary block using echogenic needle, Group N (n=30): ultrasound guided axillary block using non-echogenic needle, Group NS (n=30): ultrasound guided axillary block using non-echogenic needle with nerve stimulator assistance. Duration of block procedure, mean arterial pressure, heart rate, pulse-oximetry, onset time of sensory and motor block, duration of sensory and motor block, time to first analgesic use, total need for analgesics, postoperative pain scores, patient and surgeon satisfaction scores were recorded. RESULTS: Duration of block procedure values were lower in group E and NS, sensory and motor block durations, were significantly lower in group N. Sensorial and motor block onset time values were found lower in group NS but higher in group N. Patient and surgeon satisfaction scores were found lower in group N. CONCLUSION: We conclude that ultrasound guided axillary block may be performed successfully using both echogenic needles and nerve stimulation assisted non-echogenic needles.

OBJECTIVE: In this study, we aimed to investigate the effects of bispectral index (BIS) and neuromuscular blockade monitoring on the depth of anaesthesia and recovery in cardiac patients, scheduled to undergo open cholecystectomy operation with desflurane anaesthesia. METHODS: After the approval of the Ethics Committee and consent from the patients, patients were randomly divided into two groups. All patients received standard induction drugs, and 4-6% desflurane was used for maintenance of anaesthesia. In Group I, the anaesthesiologist was blind to BIS, and end-tidal volatile agent concentration (ETVAC) of desflurane was titrated according to the patients' hemodynamic changes. In Group II, ETVAC of desflurane was titrated to maintain BIS at 50-60. The hemodynamic data, BIS values, end-tidal volatile agent concentration (ETVAC) and train of four (TOF) values were recorded at pre-induction, post-induction, post-intubation, 1st and 5th minutes after surgical incision and then every 15 min. At the end of the operation, extubation time and the time to reach an Aldrete recovery score ≥9 were recorded in each group. Additionally, neuromuscular agent and narcotic agent doses were recorded. RESULTS: The BIS values were lower for Group I in all times, except pre- and post-induction times (p<0.05). ETVAC values of all times were lower for Group II (p<0.05). CONCLUSION: The requirement of volatile agent, which was given according to BIS monitoring, was lower than in the standard technique, but it is considered not to affect the early extubation, recovery and neuromuscular agent requirement dependent on TOF monitoring.
