Randomized Controlled Trial
Effect of Perineural Dexamethasone With Bupivacaine in Single Space Paravertebral Block for Postoperative Analgesia in Elective Nephrectomy Cases: A Double-Blind Placebo-Controlled Trial.
Various analgesic modalities have been tried to prolong the duration and to improve the quality of postoperative analgesia for the early rehabilitation and discharge from hospital after nephrectomy. Using local anaesthetic along with perineural steroids as adjuvant may prove promising for peripheral nerve block, especially paravertebral block (PVB). This article aims to assess the efficacy of dexamethasone with bupivacaine as adjuvant for single bolus injection of thoracic PVB in patients undergoing elective nephrectomy. ⋯ The total dose of intravenous fentanyl in the first 24 hours postoperatively in group D was 98.6 ± 14.14 μg as compared with 147.6 ± 18.22 μg in group B. No other significant side effects were noted except for nausea and vomiting in 5 patients of placebo group. Dexamethasone, along with bupivacaine as adjunct for thoracic PVB, helps in improving the quality and enhancing the postoperative analgesia duration in patients undergoing nephrectomy.

Randomized Controlled Trial Comparative Study
Comparison of the Clinical Effectiveness of PFNA, PFLCP, and DHS in Treatment of Unstable Intertrochanteric Femoral Fracture.
In this study, a randomized trial was conducted to compare the clinical effectiveness of proximal femoral locking compression plate (PFLCP), dynamic hip screw (DHS), and proximal femoral nail antirotation (PFNA) for unstable intertrochanteric femoral fracture treatment. Ninety patients diagnosed with unstable intertrochanteric femoral fracture were enrolled in this study at the department of orthopedics at Linyi Second People's Hospital between May 2010 and May 2012. Fractures were classified according to Tronzo-Evans classification, and the patients were randomly divided into 3 groups, PFLCP, DHS, and PFNA, with 30 patients in each group. ⋯ However, PFLCP and DHS groups did not show significant differences in the incidence of postoperative complications. Notably, the Harris hip score of PFNA group was markedly higher than the DHS group. In conclusion, our results provide convincing evidence that PFNA may be the most effective internal fixation treatment of unstable intertrochanteric femoral fracture.

Observational Study
Using Ultrasound-Guided Peripheral Catheterization of the Internal Jugular Vein in Patients With Difficult Peripheral Access.
Vascular access is necessary in patients admitted to the intensive care unit and the medical ward. Currently, there are multiple modalities to achieve adequate vascular access, each with their own difficulties and drawbacks. Often, in patients with certain comorbidities, it is difficult to obtain a peripheral intravenous (IV) line, which can lead to multiple failed attempts in achieving access. ⋯ There were no complications on follow-up. US-guided placement of peripheral IV catheters in the IJ is feasible to achieve short-term IV access in a select patient population who failed traditional peripheral IV placement. Furthermore, larger trials are needed to confirm safety and long-term complications of this method.

In patients undergoing coronary artery bypass grafting (CABG), intraoperative and postoperative major bleeding requiring blood transfusions and surgical reexploration is associated with increased mortality and morbidity. Our study hypothesized that exposure to clopidogrel is not significantly associated with increased risk for intraoperative bleeding, even when administered less than 5 days before CABG. We also aimed to determine variables associated with intraoperative packed red blood cell (iPRBC) transfusion. ⋯ The mean iPRBC transfused were 1.68 units, with higher units being transfused in women as compared with men (2.23 vs. 1.49 units, respectively, P = 0.03) and no significant difference between clopidogrel and nonclopidogrel arms (1.92 vs. 1.50, respectively, P = 0.18). After multivariate analysis, age [odds ratio (OR) = 1.03, P = 0.01], female sex (OR = 2.61, P = 0.006) and hypertension (OR = 7.10, P = 0.02) predicted increased iPRBC transfusion. Clopidogrel or nonclopidogrel status was not associated with increased iPRBC transfusion (OR = 1.06, P = 0.81). iPRBC transfusion rates were similar in both arms with age, female sex, and hypertension being an independent predictor of iPRBC transfusion.
