The reduction in pain scores is often not significant buy atorlip-20 20 mg cheap, suggesting the existence of additional pain from deep pelvic dissection and suturing of the vaginal vault during hysterectomy 78 | Ultrasound Blocks for the Anterior Abdominal Wall (Kelly 1996) atorlip-20 20mg sale. Recently cheap 20mg atorlip-20 mastercard, a trial on women undergoing pubic to umbilical midline incision for heterogeneous gynecologic malignancy buy atorlip-20 20 mg online, showed no benefit of ultrasound-guided TAPB on analgesic requirement cheap atorlip-20 20mg online, pain scores, adverse effects and satisfaction over multimodal analgesia (Griffiths 2010). Other Abdominal Surgery Procedures Andrea Pradella, Tommaso Mauri Lower Abdominal Surgery Lower abdominal surgery includes varicocelectomy, appen- dicectomy, open prostatectomy, lumbectomy and intra-aortic procedures with femoral artery cannulation. Surgical reports on awake varicocelectomy show the efficacy of local anesthetic infiltration beneath the aponeurosis of the EOM into the inguinal canal to block the ilioinguinal and genitofemoral nerves (Hsu 2005). Recently, an effective ultrasound-guided spermatic cord block was reported (Wipfli 2011). In the only randomized study in adults undergoing varicocelectomy under general anesthesia and an IIB before surgery, patients experienced significantly reduced postoperative pain scores at rest and during mobilization, less analgesic consumption, less nausea and vomiting and were all discharged at 6 hours (Yazigi 2002). The IIB and the TAPB have also been evaluated in the performance of appendicectomy. The IIB performed before surgery in children undergoing appendicectomy showed better 80 | Ultrasound Blocks for the Anterior Abdominal Wall pain scores and less analgesic consumption for 6 hours (Courrèges 1996). The reduced pain and postoperative morphine consumption effects of ultrasound-guided TAPB in appendicectomy may last for 24 hours (Niraj 2009 (2)). TAPB for laparoscopic appendicectomy in children has been shown to offer no important clinical benefit over local anesthetic port-site infiltration (Sandeman 2011). Ultrasound-guided TAPB has also been evaluated in patients scheduled for major orthopedic surgery and anterior iliac crest harvest for autologous bone graft, with pain abolished for the first 48 hours (Chiono 2010). Upper Abdominal Surgery TAPB is an effective method of blocking the sensory afferents supplying the anterior abdominal wall. However, the classical TAPB may not reliably produce analgesia above the umbilicus (Shibata 2007). The subcostal TAPB involves injection immediately inferior to the costal margin. It has been reported to provide analgesia for incisions extending above the umbilicus (Hebbard 2008). A further development of the subcostal TAPB is the possibility to place a catheter along the oblique subcostal line in the TAM plane for continuous infusion of local anesthetic (Niraj 2011, Hebbard 2010). An ultrasound-guided technique with a Tuohy epidural needle and catheter may be used in this case. Bowel surgery TAPB in adults undergoing large bowel resection via a midline abdominal incision resulted in a significant reduction of pain scores and morphine requirements for the first 24 postoperative hours (21. Other Abdominal Surgery Procedures | 81 TAPB employed for laparoscopic colonic-rectal resections reduces overall postoperative morphine (31. In a retrospective analysis of patients undergoing laparoscopic colonic-rectal resection, an ultrasound-guided TAPB significantly reduced time to the resumption of diet and postoperative hospital stay (Zafar 2010). Ultrasound-guided TAPB in patients undergoing laparoscopic cholecystectomy was associated with a significant reduction in the administration of intraoperative sufentanyl and postoperative morphine (10. Kidney surgery TAPB may reduce pain scores and morphine requirements in patients undergoing renal transplant (Jankovic 2009 (2)). Pain scores and intraoperative opioid need may be reduced for 12 hours (Mukhtar 2010). Kidney transplant recipients receiving IIB and block of T11 to 12 intercostal nerves show reduced postoperative pain and total morphine consumption (12. Subcostal bilateral TAPB with catheters compared to epidural analgesia in adult patients undergoing elective open hepatic-biliary or kidney surgery, provided no significant differences in pain scores at rest and during coughing at 8, 24, 48 and 72 h after surgery. Tramadol consumption was significantly greater in the TAP group (Niraj 2011). After the flap resection, the fibers of the EOM and IOM are separated until the TAM is visualized and local anesthetic is injected bilaterally. Similarly, patients receiving a combination of intercostal, iliohypogastric, ilioinguinal and pararectus blocks for abdominoplasty, showed successful long-term relief of pain and a significantly reduced recovery time, allowing the patient to return to normal activities and work much sooner (Feng 2010). Abdominal Midline Surgery Savino Spadaro, Tommaso Mauri The rectus sheath block (RSB) is safe, easy to learn and perform, and provides the anesthesiologist with another method for effective and long-lasting analgesia for common day-case procedures.

Antiarrhythmic Drugs and Electrical Cardioversion for Conversion to Sinus Rhythm Key points from the Results chapter of the full report are as follows. A total of 42 RCTs involving 5,780 patients were identified that assessed the use of antiarrhythmic drugs or electrical cardioversion for the conversion of AF to sinus rhythm. Thirteen studies were considered to be of good quality, 27 of fair quality, and 2 of poor quality. Only 7 studies included sites in the United States; 25 included sites in continental Europe. The study population consisted entirely of patients with persistent AF in 25 studies, entirely of patients with paroxysmal AF in 1 study, and entirely of patients for whom prior rate- or rhythm- control therapy had been ineffective in 2 studies. Figure C represents the treatment comparisons evaluated for this KQ. Overview of treatment comparisons evaluated for KQ 4 Notes: Lines running from one oval back to the same oval (e. Table E summarizes the strength of evidence for the available comparisons and evaluated outcomes. Details about the specific components of these ratings (risk of bias, consistency, directness, and precision) are available in the full report. Across outcomes and comparisons, ES-16 although the included evidence was from RCTs with an overall low risk of bias and the evidence was based on direct outcomes, some findings were limited in terms of precision and consistency, as well as by the available number of studies.

Rhythm-Control Procedures and Drugs for Maintenance of Sinus Rhythm Key points from the Results chapter of the full report are as follows. Procedural therapies: • Transcatheter PVI versus antiarrhythmic drugs o Based on eight RCTs (five good, three fair quality) involving 921 patients, transcatheter PVI is superior to antiarrhythmic drugs for maintenance of sinus rhythm over 12 months of followup in patients with paroxysmal AF (high strength of evidence). This evidence is strongest in younger patients with little to no structural heart disease and with mild or no enlargement of the left atrium. Pharmacological therapies: • Based on nine studies (one good, eight fair quality) involving 2,095 patients, amiodarone appears to be better than sotalol but no different from propafenone in maintaining sinus rhythm (low strength of evidence). ES-18 • Only one fair-quality study, a substudy of the AFFIRM (Atrial Fibrillation Follow-Up Investigation of Rhythm Management) study involving 256 patients, systematically assessed differences in all-cause mortality between AADs; it found no statistically significant difference after a mean followup of 3. A total of 83 studies met our inclusion criteria and assessed the comparative safety and effectiveness of new procedural rhythm-control therapies, other nonpharmacological rhythm- control therapies, and pharmacological agents for the maintenance of sinus rhythm in patients with AF. These were broken down into those focusing on procedural therapies and those focusing on pharmacological therapies. Procedural Therapies We identified 65 studies enrolling 6,739 patients that evaluated procedures for rhythm control that were relevant to this KQ. Thirty-one studies were rated as good quality, 32 as fair quality, and 2 as poor quality. Fourteen studies included patients from the United States, four included the United Kingdom, six included Canada, nine included Asia, four included South America, and one included Australia/New Zealand. Thirty-six studies included patients from continental Europe. Eleven included only patients with longstanding persistent AF, 17 studies included only patients with paroxysmal AF, and 4 studies included only patients with persistent AF. Finally, two studies enrolled only patients who had comorbid heart failure.
