Suprascapular nerve block prolongs analgesia after nonarthroscopic shoulder surgery but does not improve outcome.

UNLABELLED: Suprascapular nerve block (SSNB) reportedly improves analgesia and 24-h outcomes after arthroscopic shoulder surgery performed under general anesthesia. In this study, we assessed the analgesic and clinical outcome efficacy of SSNB as an adjunct to interscalene brachial plexus block (ISB) for ambulatory nonarthroscopic shoulder surgery. Fifty patients were randomized to receive either a SSNB or sham injection as part of a standardized ISB-general anesthesia regimen. Time to first significant pain (the primary outcome measure) was significantly delayed in the SSNB group (594 +/- 369 min versus 375 +/- 273 min, respectively; P = 0.02). There were no other differences between groups with regard to postanesthesia recovery unit measures, 24-h assessment of pain, supplemental analgesic use, or quality of life outcomes. We conclude that adjunctive SSNB adds minimal value to a primary ISB anesthetic for nonarthroscopic shoulder surgery. IMPLICATIONS: When used as an adjunct to an interscalene block combined with general anesthesia, suprascapular nerve block with bupivacaine moderately prolongs analgesia without improving other outcome measures after ambulatory nonarthroscopic shoulder surgery.

Prospective comparison of continuous femoral nerve block with nonstimulating catheter placement versus stimulating catheter-guided perineural placement in volunteers.

BACKGROUND AND OBJECTIVES: Stimulating catheter-guided perineural placement may potentially increase the success rate and quality of continuous femoral nerve block as compared with a nonstimulating catheter technique. These hypotheses have not been rigorously tested. METHODS: Twenty volunteers underwent placement of bilateral femoral nerve catheters in this prospective, randomized, double-blind study. For each side, a stimulating needle was advanced until quadriceps contractions were obtained at < or =0.5 mA. On one side, a stimulating catheter was advanced 4 to 5 cm beyond the needle tip while eliciting quadriceps contractions via the catheter. If quadriceps contractions decreased or disappeared, the catheter position was adjusted until quadriceps contractions could be elicited at < or =0.5 mA. On the contralateral side, an identical catheter was advanced 4 to 5 cm beyond the needle tip without attempts to elicit quadriceps contractions via the catheter. After bolus injection of 10 mL lidocaine 1%, ropivacaine 0.2% at 10 mL/h was continuously infused through both catheters for 4 hours. Success of femoral block was defined as loss of sensation to cold and pinprick stimuli. Quality of successful block was determined by tolerance to transcutaneous electrical stimulation and force dynamometry of quadriceps strength. RESULTS: Block success was 100% via the stimulating catheters versus 85% via the nonstimulating catheters (P =.07). Overall tolerance to transcutaneous electrical stimulation (P =.009) and overall depth of motor block (P =.03) was significantly higher in the stimulating catheter-guided femoral nerve blocks. CONCLUSIONS: In this volunteer study, there was no statistically significant difference in block success between the two techniques. However, stimulating catheter-guided placement provided an increased overall quality of continuous femoral perineural blockade. Further studies are needed to verify these observations in the clinical setting.

The training and careers of regional anesthesia fellows--1983-2002.

BACKGROUND AND OBJECTIVES: The education and subsequent careers of regional anesthesia fellows have not been examined but may provide insight into improving future fellowship training and/or the future of the subspecialty. METHODS: Regional anesthesia fellows educated during a 20-year period (1983-2002) were asked to complete a comprehensive survey that detailed their training, current professional setting, and use of regional anesthesia, and how they foresee the future of regional anesthesia. A separate survey of academic anesthesiology chairs assessed the role of and need for regional anesthesiologists in teaching departments. RESULTS: Twelve regional anesthesia fellowship programs in the United States and Canada provided contact information on 176 former fellows. The survey response rate from those practicing in North America was 49% (77/156). Two of the 12 responding institutions have trained 68% of regional anesthesia fellows. Of respondents, 61% are or have been in academic practice. Regional anesthesia remains an integral part of most respondents' current practice, as evidenced by significant use of regional techniques, active involvement in subspecialty societies, and participation in continuing medical education programs. Academic chairs indicate that fellowship-trained regional anesthesiologists play important roles in resident education and are in demand by academic departments. CONCLUSIONS: This report details how regional anesthesia fellows from 1983 to 2002 were trained and how they currently practice and examines their insights regarding the strengths and weaknesses of past and future regional anesthesia education.

Guidelines for regional anesthesia fellowship training.

BACKGROUND: The number of regional anesthesia fellowships has grown over the past 2 decades. There currently exist no guidelines for what constitutes ideal regional anesthesia fellowship training. METHODS: Regional anesthesia fellowship program directors and other advocates of regional anesthesia were invited to participate in a collaborative project to establish a standardized curriculum for regional anesthesia fellowships. Guidelines were created based on the existing template of Accreditation Council of Graduate Medical Education program requirements for residency education in anesthesiology. The resulting draft guidelines were distributed at a meeting of the program directors, who were then asked to forward all comments and relevant training material from their respective institutions to a coordinating institution. RESULTS: All received materials were reviewed, and selected components were collated into a consensus document, which was then reviewed, modified, and eventually approved by the program directors over a 2-year series of meetings. The program directors agreed to adopt the guidelines as their fellowship curriculum and to evaluate their effectiveness in 2 years' time. CONCLUSIONS: The intent of these initial guidelines is to improve the quality and consistency of regional anesthesia fellowship training. The creation process also led to an affirmation of the directors' commitment to continued dialogue for the purpose of facilitating the exchange of ideas among programs.

Near-total esophagectomy: the influence of standardized multimodal management and intraoperative fluid restriction.

BACKGROUND AND OBJECTIVES: Esophagectomy can be associated with high morbidity and mortality. We present our experience managing these patients using a standardized multimodal approach that emphasizes intraoperative fluid restriction and early extubation. METHODS: This case series includes 56 consecutive patients over a 2-year period (1999-2000) that underwent near-total esophagectomy at a high-volume center. Surgical approach was determined by patient and tumor characteristics; intraoperative fluid replacement was conservative; and patient-controlled epidural anesthesia/analgesia was used to promote early extubation, enteral feeding, and ambulation. RESULTS: Overall morbidity was 18%; in-hospital and 30-day mortality was zero. Intraoperative urinary volume averaged 0.57 mL/kg/h. No patient developed postoperative renal dysfunction or pulmonary complications. All patients were extubated in the operating room. First ambulation averaged 1.6 days after surgery. Median intensive care unit and hospital stays were 1 and 10 days, respectively. Side effects from thoracic epidural analgesia were minimal. CONCLUSIONS: Significant reduction in esophagectomy-related morbidity is possible using a standardized multimodal approach in routine clinical practice. Intraoperative fluid restriction may facilitate early extubation and reduce pulmonary complications without compromising renal function. This preliminary observation warrants further study in a randomized clinical trial.

Regional anesthesia and pain medicine: residency training--the year 2000.

BACKGROUND AND OBJECTIVES: A survey of anesthesiology training programs in 1980 reported the use of a regional anesthetic technique in 21.3% of cases. A similar survey of anesthesiology training programs in 1990 reported that the use of regional anesthetic techniques had increased to 29.8%. Over the ensuing 10 years, additional changes have occurred in the field of anesthesiology and its United States residency training programs. This manuscript reports the impact these changes have had on the use of regional anesthesia techniques in residency training programs in the year 2000. METHODS: Blinded cumulative data about regional anesthetic techniques performed by anesthesiology residents were obtained from all annual training report forms submitted to the Residency Review Committee for Anesthesiology. Exposure to obstetric (OB) anesthesia, pain management, and a resident's year-in-training were analyzed as independent factors expected to influence the use of regional anesthesia. RESULTS: Anesthesiology trainees used a regional anesthesia technique in 30.2% of cases in the year 2000. This represents an insignificant change from 1990 and a marked slowing in the growth of regional anesthesia techniques compared with the 1980 to 1990 period. The use of regional anesthesia remains strongly correlated with a resident's exposure to OB anesthesia and pain consultations. Variability in exposure to regional anesthesia techniques among individual residents has decreased. CONCLUSIONS: Anesthesiology training programs now appear to provide a satisfactory exposure to regional anesthesia for a majority of resident trainees, although 40% of residents may still be deficient in nerve block anesthesia. The growth in the use of regional anesthesia during residency has plateaued over the past decade, but the discrepancy between individual resident experience has improved.

Assessment of lower extremity nerve block: reprise of the Four P's acronym.

BACKGROUND AND OBJECTIVES: Successful performance of lower-extremity regional anesthesia includes sensory and/or motor block assessment of up to 4 major peripheral nerves. This brief report describes a methodology for the rapid evaluation of lower-extremity anesthesia before surgical incision. METHODS: Illustrations highlight the techniques for evaluation of sciatic, obturator, lateral femoral cutaneous, and femoral nerve anesthesia. This methodology is based on a Four P's acronym: push, pull, pinch, punt. CONCLUSIONS: Accurate assessment of lower-extremity regional anesthesia can be achieved rapidly using The Four Ps evaluation tool.
