The aim was to examine intraocular pressure (IOP) during lumbar spine surgery in PP under general vs spinal anesthesia and to compare it with volunteers in PP. Materials and methods: We performed randomized prospective single institutional trial. Patients were operated in PP with fixation of 1-2 spinal segments. Patients of group I (n = 30) were operated under SA, group 2A (n = 25) – under TIVA (total intravenous anesthesia) with 45° head rotation (left eye was located lower, than right eye), group 2B (n=25) – under TIVA with no head rotation (both eyes were located on the same level). IOP was measured with Maklakov method before and after surgery. Volunteers (n = 20) were examined before and 90 minutes after lying in PP with 45° head rotation. Results: In all patients and volunteers after lying in PP, we found that IOP have increased. In SA patients and in TIVA patients with no head rotation there was no difference between eyes. The most significant raise of IOP was found in the dependent eye of IIA group patients: it was higher than in volunteers and I group patients (p < 0.01), and IIB group patients (p < 0.05). In SA patients there was no difference in IOP comparing to volunteers. Conclusions: IOP increased in PP in healthy people and patients under anesthesia (SA and TIVA). IOP in SA patients did not differ from volunteers. IOP increased superiorly in the dependent eye in TIVA patients.

Multimodal analgesia for lumbar spine surgery is still a controversial problem, because of possible fusion problems, significant neuropathic component of pain, and influence of anesthesia type. Aim of the study was to assess the efficacy of pain management after lumbar spine surgery considering characteristics of pain, type of anesthesia and analgesic regimen. Material and methods. 254 ASA I-II patients with degenerative lumbar spine disease were enrolled into prospective study. Patients were operated either under spinal anesthesia (SA) or total intravenous anesthesia (TIVA). In postoperative period patients got either standard pain management (SPM – paracetamol±morphine) or multimodal analgesia (MMA – paracetamol+parecoxib+pregabalin±morphine). Results. We revealed neuropathic pain in 53.9 % of patients, who were elected for lumbar spine surgery. VAS pain score in patients with neuropathic pain was higher, than in patients with nociceptive pain. Total intravenous anesthesia was associated with greater opioid consumption during the first postoperative day. Multimodal analgesia based on paracetamol, parecoxib and pregabalin allowed to decrease requirements for opioids, postoperative nausea and dizziness. Pregabalin used for evening premedication had equipotential anxiolytic effect as phenazepam without postoperative cognitive disturbances. Conclusions. Multimodal analgesia is opioid-sparing technique that allows to decrease complications. Spinal anesthesia is associated to a decreased opioid consumption in the 1st postoperative day.

AbstractPrimary hypoparathyroidism and consequent hypocalcaemia in the absence of iatrogenic cause are a rare entity. Serum ionised calcium concentrations < 0.50 mmol l−1 are more frequently associated with life-threatening complications and constitute a medical emergency that necessitates intravenous calcium therapy. The anaesthesiologist should carefully look for the effects of hypocalcaemia on the heart, circulation, muscle power and blood coagulation. We report perioperative management of a case of hypoparathyroidism and associated hypocalcaemia posted for lumbar discectomy in prone position and its anaesthetic implications.

Abstract INTRODUCTION Lumbar spine surgery can be successfully performed using various anesthetic techniques. Previous studies have shown varying results in selected outcomes when directly comparing spinal anesthesia (SA) to general anesthesia (GA) in lumbar surgery. We sought to elucidate the more expedient anesthetic technique. METHODS Following IRB approval, a retrospective review of patients undergoing elective lumbar decompression surgery using GA or SA was performed. Demographic data known to influence perioperative morbidity was collected as well as safety and efficiency parameters. After controlling for patient and procedure characteristics, simple linear and multivariate regression analyses were performed to identify differences in operative blood loss, operative time, time from entering the OR until incision, time from bandage placement to exiting the OR, total anesthesia time, time in the post-anesthesia care unit (PACU), and length of hospital stay. RESULTS >544 consecutive lumbar laminectomy and discectomy surgeries were identified with 183 undergoing GA and 361 undergoing SA. The following times were all shorter for patients receiving SA than GA: operative time (97.4 vs. 151.8 min., P < 0.001), total anesthesia time (145.6 vs. 217.5 min., P < 0.001), time from entering the OR until incision (38.3 vs. 46.8 min., respectively, P < 0.001), time from bandage placement until exiting the OR (10.2 vs. 17.2 min., P < 0.001), and length of hospital stay (1.5 vs. 3.1 days, P < 0.001). The mean PACU length of stay was longer in the SA group than the GA group (178.0 vs. 116.5 min., P < 0.001). Estimated blood loss was less in the SA group than the GA group (62.1 vs. 176.3 mL, P < 0.001). CONCLUSION Spinal anesthesia may be the more expedient method of anesthesia in lumbar spinal surgery for all perioperative time points except for time in the PACU.
