Objective The consumption of opioid analgesics could be reduced by the use of analgesics with different mechanisms of action. We investigated whether additional treatment with dexmedetomidine or lidocaine could reduce opioid consumption. Methods We randomized 59 study participants into three groups and examined: (i) fentanyl consumption, (ii) consumption of piritramide, and (iii) cognitive function and neuropathic pain. The control group received continuous propofol infusion and fentanyl boluses. Continuous intravenous infusion of dexmedetomidine (0.5 µg/kg/h) was administered to the dexmedetomidine group and lidocaine (1.5 mg/kg/h) was administered to the lidocaine group. Results No reduction in fentanyl consumption was observed among the groups. However, we noted a significantly lower consumption of piritramide on the first and second postoperative day in the lidocaine group. Total consumption of piritramide was significantly lower in the lidocaine group compared with the control group. Conclusions Lidocaine and dexmedetomidine reduced intraoperative propofol consumption, while lidocaine reduced postoperative piritramide consumption. Clinical trial registration: NCT02616523

To compare the effects of paravertebral analgesia with levobupivacaine or bupivacaine on intra- and postoperative pain for thoracic surgery.A prospective, randomized, and double-blinded study.A university hospital.Forty patients undergoing thoracic surgery.Patients received paravertebral catheterization and a bolus (14-20 mL) of 0.5% bupivacaine (n = 20) or 0.5% levobupivacaine (n = 20) with morphine, 60 μg/kg, before the induction of general anesthesia that consisted of a propofol infusion. A paravertebral continuous infusion (0.05 mL/kg/h) of 0.25% bupivacaine or 0.25% levobupivacaine, 100 mL, with added morphine, 10 mg, and clonidine, 0.15 mg, was started at the end of surgery for 72 hours postoperatively. Postoperative rescue diclofenac analgesia was available if required.The primary outcome was intraoperative fentanyl consumption. Static and dynamic pain scores measured by a visual analog scale were assessed regularly. Intraoperative fentanyl consumption was significantly lower in the levobupivacaine group compared with the bupivacaine group (p = 0.001). On all 3 postoperative days, static pain scores were significantly lower in the levobupivacaine group compared with the bupivacaine group (p0.05). Dynamic pain scores were significantly lower in the levobupivacaine group compared with the bupivacaine group during the 2 postoperative days (p0.05). A smaller proportion of patients in the levobupivacaine group used rescue analgesia (p0.005).Paravertebral analgesia with levobupivacaine resulted in less intraoperative fentanyl consumption, lower static (3 days) and dynamic (2 days) pain scores, and less rescue analgesia than analgesia with bupivacaine.

Launois-Bensaude syndrome, otherwise known as Madelung's disease, is a rare disorder characterized by fatty accumulations of the upper trunk, neck and head, causing serious cosmetic deformity and neck immobility. We report a case of a patient with Launois-Bensaude syndrome who required 4 different airway management strategies during his hospitalization for postoperative complications after an elective surgical excision of a severe neck lipomatosis. Anesthesiologists who treat patients with Madelung's disease should be aware of 2 major problems: difficult airway and increased frequency of postoperative bleeding. A proper choice of airway management technique is therefore necessary, including a safe intubation and extubation plan to reduce the consequences of airway complications.

Background. For some surgical proce-dures a higher sensory block is needed. However, it is complicated by a higher in-cidence of hypotension, more bradycardia and nausea and a higher use of vasoactive drugs. In elderly and obstetric population complications have been attributed to the decrease in cardiac output and systemic vascular resistance, especially in a high block (above Th6). The aim of our study was to find the incidence of hypotension and bradycardia after a spinal anaesthesia in young, healthy patients. As young pa-tients compensate more, we aimed to find the difference in haemodynamic variables between the group with a high and the group with a low spinal block and the un-derlying mechanisms of hypotension. Methods. In a prospective, randomized study 44 American Society of Anaesthe-siologists (ASA) 1 patients scheduled for knee arthroscopy under spinal anaesthe-sia were randomly distributed to a high (group H) and a low (group L) spinal block group. In a group H patients were placed into horizontal, whereas in a group L in 15-degree anti-Trendelenburg posi-tion immediately after the spinal block. Haemodynamic parameters were meas-ured continuously noninvasively from 10 min before to 25 min after the spinal block using the CNAPTM device with the LiD-CORapid monitor.Results. The differences in haemodynamic parameters between the groups were not statistically significant at all measured times despite a significant difference in the spinal block level (18.5 vs 13.3 dermato-mes above S5, p
