Purpose. In a randomized, double-blind trial, the efficacy of nonopioid analgesics on postoperative piritramide consumption was compared for pain relief during the first 24 h in patients recovering from arthroscopic knee surgery. Methods. 120 patients were treated with normal saline and/or one of the nonopioid analgesics (parecoxib, metamizole, paracetamol) in addition to piritramide using the PCA pump. Beginning in the postanesthesia care unit (PACU), patients were asked to quantify their pain experience at rest while piritramide consumption was recorded. Results. Piritramide consumption upon arrival in the PACU was high in all groups. However, cumulative consumption in the parecoxib group was significantly lower than that in the placebo group at 6 and 12 h after surgery. At discharge from the PACU, VAS scores dropped in all groups and were significantly lower in the parecoxib group. In the PACU, satisfaction of the patients was moderate and improved with time after surgery. Conclusions. There was statistically significant opioid-saving effect by administering parecoxib with better VAS scores and satisfaction level compared to placebo. The high pain score in the PACU in all groups immediately after recovering from remifentanil-based anesthesia would be prevented if local anesthetics were administered intra-articularly as part of a multimodal analgesic approach.

Background: Post-dural puncture headache (PDPH) is the most common complication of procedures in which the dura mater is penetrated. Objectives: To evaluate the effectiveness of caudal saline injections as a therapeutic approach for handling post-dural puncture headache. Study Design: Prospective observational study between 1995 and 2010. Setting: Associated teaching hospital. Methods: A 5-cm 20-gauge short-beveled needle, connected by extension tube to a 20- mL syringe filled with normal saline was used for injection. During injection in increments (limited by patient discomfort), the patients were asked continually to quantify their pain experience on a visual analog scale (VAS) and on a 0-3 verbal categorical rating scale (VRS) after 50, 80 and 100 mL of infusion over a 20 minute period. Limitations: This study is limited by its sample size, observational design, and lack of long-term outcomes. Results: PDPH occurred in 60 of 1,716 patients undergoing dural puncture (3.5%). It was significantly more common in women and occurred more often in young adults. The rate was highest in the spinal catheter group (13%) and lowest in the Sprotte needle group (0.98%). Fifty-six patients underwent caudal saline injections which were repeated in sessions of 1-2 times a day for 1-2 days. Most patients (n = 48) needed 3 or 4 (n=18) sessions. Mean volumes during the 4 sessions were 120.0 mL, 114.9 mL, 106.5 mL, and 97.8 mL. Four patients were finally treated with a blood patch. Conclusions: The use of fine gauge pencil-point needles may reduce the incidence of PDPH. The technique of repeated caudal saline injections is easy, rapid, and effective in providing the patient with almost immediate headache relief. In cases where this treatment fails, a blood patch should be considered. Observations from this study suggest that randomized, controlled, double-blind studies may be warranted. Key words: Post-dural puncture headache (PDPH), dural puncture, spinal anesthesia, caudal saline injection

Background:Difficult intubation, most often due to poor view of the vocal cords on laryngoscopy is an intermittent and often challenging problem for clinically practicing anesthesiologists, maxillofacial surgeons, ear nose, and throat (ENT), emergency, and critical care physicians.Purpose:We present a new approach for facilitating difficult intubation and evaluate its efficacy in a retrospective observational study.Settings and Design:Operating room, emergency department, intensive care unit (ICU), retrospective observational study.Materials and Methods:A semirigid 5.6 Rüsch tracheal tube introducer (bougie) with its soft tip protruding at least 6 cm (=4 digits) beyond the distal end of the tube was used. After its insertion through the larynx under laryngoscopy, the tube was gently advanced upon rotation at 360° clockwise.Statistical Analysis:Descriptive.Results:Anesthesia services were analyzed on 10,363 patients over 12 months. In 2453 patients (23.7%) (Group A) intubated in the usual way, difficulties were encountered in 63 patients (2.6%). They were managed either with tube rotation technique (n = 60) or Bonfils endoscope (n = 3). In contrast, 2807 patients (27.1%) (Group B) were intubated using tube rotation technique with introducer. Difficult intubations occurred only in three patients (0.11%) who could be managed with tube rotation by experienced consultant anesthesiologists.Conclusions:The tube rotation technique for intubation was introduced during the Gulf War and has been practiced for the past 19 years without any obvious damage to the trachea in Germany. However, it should be used only by physicians being well familiar with this technique. In addition, well designed controlled studies are needed.
