The purpose of this study was to explore the effects of three different ventilatory modes: volume controlled ventilation (VCV), pressure controlled ventilation (PCV) and pressure controlled ventilation-volume guaranteed (PCV-VG) on arterial oxygenation and airway pressure during one-lung ventilation (OLV) in elderly patients. ⋯ Compared with VCV, the use of PCV and PCV-VG have a significant advantage in intraoperative oxygenation and airway pressure for eldly patients undergoing OLV.

The aim of the study was to investigate the changes of the lumbar intervertebral disc degeneration by magnetic resonance imaging (MRI) after the implantation of interspinous device and the fusion of the adjacent segment. A total of 62 consecutive patients suffering L5/S1 lumbar disc herniation (LDH) with concomitant disc space narrowing or low-grade instability up to 5 mm translational slip in L5/S1 level were treated with lumbar interbody fusion (LIF) via posterior approach. Thirty-four of these patients (Coflex group) received an additional implantation of the interspinous spacer device (Coflex™) in the level L4/L5, while the rest of 28 patients (fusion group) underwent the fusion surgery alone. ⋯ Although both Coflex and fusion group showed improvements of the clinical outcomes assessed by the Oswestry Disability Index (ODI) after surgery, patients in Coflex group had more significant amelioration (P < 0.05) compared to fusion group. During follow up, the postoperative disc degeneration changes in Coflex group assessed by the relative signal intensity (RSI) differed from those in fusion group (P < 0.05). The supplemental implantation of Coflex™ after the fusion surgery could delay the disc degeneration of the adjacent segment.

Sufentanil-induced cough is a common phenomenon during the induction of anesthesia. This double-blind, randomized, and placebo-controlled study was designed to investigate the effects of prophylactic magnesium sulfate (MgSO4) on the incidence and severity of sufentanil-induced cough. A total of 165 patients who were scheduled for elective surgery under general anesthesia were allocated into three groups (I, II, and III; n = 55 each) that were injected with either 50 ml of normal saline, 30 or 50 mg/kg of MgSO4 (diluted with normal saline into 50 ml). ⋯ Compared with group I, group III had the lowest incidence of mild cough and both groups II and III had lower incidence of moderate and severe cough (P < 0.05). There were no differences in the hemodynamic data at three timepoints among the three groups. In conclusion, sufentanil-induced cough may be suppressed effectively and safely by prophylactic use of 30 mg/kg of MgSO4 during anesthetic induction.

Locking of central venous catheters with heparin is an accepted practice to maintain catheter patency between dialysis sessions. However, this practice may cause other adverse reactions. Although many studies suggest benefits of other catheter lock solutions over heparin on these grounds, no consensus has been reached for clinical practice. ⋯ Compared with heparin, antimicrobial-containing lock solutions more effectively prevent CRB and clinical sepsis. Antibiotics + heparin and gentamicin + citrate solutions showing better prevention of CM. Citrate-alone lock solutions result in fewer CRB, bleeding and ESI episodes.

To determine the pathogenesis and characteristics and to assess the long-term effectiveness of polymethylmethacry late (PMMA) vertebroplasty treatment in patients with intravertebral cleft (IVC) in osteoporotic compression fractures. ⋯ Polymethylmethacrylate vertebroplasty treatment of osteoporotic compression fractures is initially effective for patients with signs of IVC, but compression and kyphosis gradually reoccur. Therefore, we strongly recommend strict observation and follow-up after vertebroplasty.
