At present, posterior interbody fusion surgery with pedicle internal fixation is the gold standard for the treatment of lumbar degenerative disc diseases. However, an increasing number of studies have shown that because fused lumbar vertebrae lose their physiological activity, the compensatory range of motion (ROM) of the adjacent levels increases. To address this issue, dynamic internal fixation systems have been developed. ⋯ The treatment of lumbar degenerative disc diseases with the Isobar TTL dynamic internal fixation system can effectively relieve pain, improve quality of life, and preserve the lumbar ROM of the stabilized segment with a satisfactory clinical therapeutic effect.

Observational StudyAdverse Drug Effects and Preoperative Medication Factors Related to Perioperative Low-Dose Ketamine Infusions.
High-dose opioid administration is associated with significant adverse events. Evidence suggests that low-dose ketamine infusions improve perioperative analgesia over conventional opioid management, but usage is highly variable. ⋯ The purposes of this study were 3-fold: (1) to identify patient factors associated with initiation of ketamine infusions during spine surgery, (2) to identify specific spine procedures in which ketamine has been used most frequently, and (3) to identify ADEs associated with postoperative ketamine infusions and which ADEs most frequently led to discontinuation. Spine surgery was chosen because of its association with moderate to severe pain and a relatively high use of ketamine infusions in this population at our hospital.

CommentMagnesium sulfate for postoperative analgesia after surgery under spinal anesthesia.
Magnesium has been proven to have antinociceptive effects in animal and human models of pain. Its effect is primarily based on the regulation of calcium influx into the cell, which is natural physiological calcium antagonism and N-methyl-d-aspartate (NMDA) receptor antagonism. ⋯ Intravenous magnesium sulfate when given as a bolus, followed by an infusion, delayed and decreased the need of rescue analgesics after spinal anesthesia.

The use of lung-protective ventilation (LPV) strategies may minimize iatrogenic lung injury in surgical patients. However, the identification of an ideal LPV strategy, particularly during one-lung ventilation (OLV), remains elusive. This study examines the role of ventilator management during OLV and its impact on clinical outcomes. ⋯ Low VT per se (i.e., in the absence of sufficient PEEP) has not been unambiguously demonstrated to be beneficial. The authors found that a large proportion of patients continue to receive high VT during OLV and that VT was inversely related to the incidence of respiratory complications and major postoperative morbidity. While low (physiologically appropriate) VT is an important component of an LPV strategy for surgical patients during OLV, current evidence suggests that, without adequate PEEP, low VT does not prevent postoperative respiratory complications. Thus, use of physiologic VT may represent a necessary, but not independently sufficient, component of LPV.
