Monitoring low molecular weight heparins (LMWH's) in the perioperative period is prudent in patients at high risk of coagulative complications, especially when the patient has an epidural catheter requiring withdrawal, which is associated with the risk of spinal haematoma. The aim of this study was to evaluate the in vitro dose-responses of two different LMWH's on two different viscoelastic haemostatic tests, using blood sampled from patients with normal routine coagulation parameters, on the day after major surgery when their epidural catheters were due to be withdrawn. ⋯ Clot initiation time's dose-dependent prolongation by LMWH's in this study agrees with previous research, as does tinzaparin's stronger anti-coagulative effect than enoxaparin at equivalent levels of anti-FXa activity. This casts doubt on the validity of using anti-FXa assays alone to guide dosage of LMWH's. The significant inter-individual variation in dose-response suggests that the relationship between dose and effect in the postoperative period is complicated. While both ROTEM and FOR may have some role in postoperative monitoring, more research is needed before any conclusion can be made about their clinical usefulness.

Abrupt cessation of intrathecal baclofen can lead to a serious withdrawal syndrome. The anesthesiologist must be prepared to avoid intraoperative interruption of baclofen delivery before starting spinal surgery and to recognize and treat the symptoms of baclofen withdrawal in the immediate postoperative period.

Randomized Controlled Trial Comparative Study
Administration of paracetamol versus dipyrone by intravenous patient-controlled analgesia for postoperative pain relief in children after tonsillectomy.
We compared the efficacy of intravenous (IV) paracetamol versus dipyrone via patient-controlled analgesia (PCA) for postoperative pain relief in children. ⋯ Paracetamol and dipyrone have well tolerability profile and effective analgesic properties when administered IV-PCA for postoperative analgesia in children after tonsillectomy.

Percutaneous kyphoplasty (PKP) has been proven as an effective, minimally invasive procedure for the treatment of Kummell's disease in the early stages. However, a risk of cement leakage and further neurological damage remains during and after PKP, especially in chronic osteoporotic stage III Kummell's disease with severe spinal canal stenosis. ⋯ PKP is an effective, minimally invasive procedure for the treatment of chronic osteoporotic stage III Kummell's disease with severe spinal stenosis, leading to a significant relief of symptoms and improvement of functional status. INSTITUTIONAL REVIEW: This study was approved by the Institutional Review Board.
