New variables for measuring joint space width to evaluate knee osteoarthritis.
Assessing the radiographic features of knee osteoarthritis (OA), especially joint space narrowing, is important for evaluating disease progression. The purpose of this study was to quantitatively analyze joint space narrowing by measuring 2 new variables: the average joint space width (aJSW) and the articulate angle (AA) on X-ray films, and to evaluate the relationship between the 2 variables, knee function and OA symptoms. ⋯ The aJSW closely correlated with knee OA symptoms and function scores, and was more sensitive to knee OA related disabilities than K-L grade and the AA. The aJSW could be used as a new variable for knee OA evaluation.

To lessen the occurrence of contrast-induced nephropathy (CIN), the preventive measures of CIN were reviewed. ⋯ Pericatheterization hydration, discontinuation of nephrotoxic drugs, and using the lowest possible dose of CM are effective measures to lessen the risk for CIN. Other prophylactic strategies and some drugs are promising, but further confirmation is required.

Randomized Controlled TrialMinimally invasive lumbar interbody fusion via MAST Quadrant retractor versus open surgery: a prospective randomized clinical trial.
In recent years, a variety of minimally invasive lumbar surgery techniques have achieved desirable efficacy, but some dispute remains regarding the advantages over open surgery. This study aimed to compare minimally invasive lumbar interbody fusion via MAST Quadrant retractor with open surgery in terms of perioperative factors, postoperative back muscle function, and 24-month postoperative follow-up results. ⋯ MIS can effectively reduce sacrospinalis muscle injury compared with open surgery, which is conducive to early functional recovery. In the short term, MIS is superior to open surgery, but in the long term there is no significant difference between the two procedures.

Clinical TrialA pilot study of the effect of pressure-driven lidocaine spray on airway topical anesthesia for conscious sedation intubation.
Difficult airway remains not only a challenge to the anesthesiologists, but also a life-threatening event to the patients. Awake intubation is the principal choice to deal with difficult airway, and a key point for awake intubation is airway topical anesthesia. Yet, so far there is no ideal topical anesthesia approach for awake intubation. This study aimed at evaluating the effect of pressure-driven (by 10 L/min oxygen flow) lidocaine spray on airway topical anesthesia in order to find a powerful and convenient method for airway topical anesthesia for conscious sedation intubation. ⋯ Topical anesthesia with pressure driven 2% lidocaine spray, where pressure is achieved by 10 L/min oxygen flow, can offer satisfactory intubation conditions for conscious sedation intubation.

Clinical TrialEvaluation of high-concentration sevoflurane for induction and nasotracheal intubation without muscle relaxant for infants with different pulmonary blood flow undergoing surgery for congenital heart diseases.
Inhalational anesthesia with sevoflurane for endotracheal intubation without muscle relaxant is now used widely for pediatric patients. This study assessed the efficacy and safety of induction with high concentration sevoflurane and of nasotracheal intubation without muscle relaxant in infants with increased or decreased pulmonary blood flow (PBF) and undergoing surgery for congenital heart diseases. ⋯ Induction with high concentration sevoflurane, although faster for infants with IPBF, is safe for infants with IPBF or DPBF. However, nasotracheal intubation without muscle relaxant after induction with high concentration sevoflurane is less successful and less satisfactory for infants with DPBF and should be used with caution in this patient group.
