Bilateral infraorbital nerve blocks decrease postoperative pain but do not reduce time to discharge following outpatient nasal surgery
While infraorbital nerve blocks have demonstrated analgesic benefits for pediatric nasal and facial plastic surgery, no studies to date have explored the effect of this regional anesthetic technique on adult postoperative recovery. We designed this study to test the hypothesis that infraorbital nerve blocks combined with a standardized general anesthetic decrease the duration of recovery following outpatient nasal surgery.
At a tertiary care university hospital, healthy adult subjects scheduled for outpatient nasal surgery were randomly assigned to receive bilateral infraorbital injections with either 0.5% bupivacaine (Group IOB) or normal saline (Group NS) using an intraoral technique immediately following induction of general anesthesia. All subjects underwent a standardized general anesthetic regimen and were transported to the recovery room following tracheal extubation. The primary outcome was the duration of recovery (minutes) from recovery room admission until actual discharge to home. Secondary outcomes included average and worst pain scores, nausea and vomiting, and supplemental opioid requirements.
Forty patients were enrolled. A statistically significant difference in mean [SD] recovery room duration was not observed between Groups IOB and NS (131 [61] min vs 133 [58] min, respectively; P = 0.77). Subjects in Group IOB did experience a reduction in average pain on a 0–100 mm scale (mean [95% confidence interval]) compared to Group NS (−11 [−21 to 0], P = 0.047), but no other comparison of secondary outcomes was statistically significant.
When added to a standardized general anesthetic, bilateral IOB do not decrease actual time to discharge following outpatient nasal surgery despite a beneficial effect on postoperative pain

A portable mechanical pump providing over four days of patient-controlled analgesia by perineural infusion at home.
Background and objectivesLocal anesthetics infused via perineural catheters postoperatively decrease opioid use and side effects while improving analgesia. However, the infusion pumps described for outpatients have been limited by several factors, including the following: limited local anesthetic reservoir volume, fixed infusion rate, and inability to provide patient-controlled doses of local anesthetic in combination with a continuous infusion. We describe a patient undergoing open rotator cuff repair who was discharged home with an interscalene perineural catheter and a mechanical infusion pump that allowed a variable rate of continuous infusion, as well as patient-controlled boluses of local anesthetic for over 4 days.Case reportA 77-year-old woman, who had previously required a 3-day hospital admission for acute postoperative pain following an open repair of her left rotator cuff, presented for an open repair of her contralateral rotator cuff. Preoperatively she received an interscalene block and perineural catheter. After the procedure she was discharged home with a portable pump that infused ropivacaine continuously at a rate of 6 mL/h and allowed a 2-mL patient-controlled bolus every 20 minutes (550-mL reservoir). The basal infusion was decreased, as tolerated, by having the patient reprogram the pump with instructions given over the telephone. Without the use of any oral opioids, the patient scored her surgical pain 0 to 1 (on a scale of 0 to 10) while at rest and 2 to 3 for 2 physical therapy sessions during which she used the bolus function to reinforce her analgesia. After 98 hours of infusion, the patient's husband removed the catheter with instructions given over the telephone, and her subsequent surgical pain was treated with oral opioids.ConclusionContinuous, perineural local anesthetic infusions are possible on an ambulatory basis for multiple days using a portable, programmable pump that provides a variable basal infusion rate, patient-controlled boluses, and a large anesthetic reservoir

Continuous Interscalene Block for Postoperative Analgesia and Shoulder Immobilization After Pectoralis Major Tendon Reinsertion: A Case Report.
We present the case of a 38-year-old man undergoing surgical repair of his pectoralis major tendon. An interscalene catheter was placed between the middle and lower trunks of the brachial plexus. Postoperatively, ropivacaine 0.2% was infused through postoperative day 3. The patient had excellent pain control requiring minimal opioid analgesics. A catheter between the middle and lower trunks of the brachial plexus provided excellent postoperative analgesia after pectoralis major tendon reinsertion. Additionally, the block likely protected the surgical repair during emergence from anesthesia and in the early postoperative period by providing a motor block of the pectoralis major muscle

Continuous infraclavicular brachial plexus block for postoperative pain control at home: a randomized, double-blinded, placebo-controlled study.
BackgroundThis randomized, double-blinded, placebo-controlled study investigated the efficacy of patient-controlled regional analgesia using an infraclavicular brachial plexus perineural catheter and a portable infusion pump for outpatients undergoing moderately painful, upper extremity orthopedic surgery.MethodsPreoperatively, patients (n = 30) received an infraclavicular nerve block and perineural catheter. Postoperatively, patients were discharged home with oral narcotics and a portable infusion pump delivering study solution (0.2% ropivacaine or 0.9% saline) via the catheter for 3 days. Investigators and patients were blinded to random group assignment. Daily end points included pain scores at rest and with limb movement, narcotic use and side effects, sleep quality, patient satisfaction, and symptoms of catheter- or local anesthetic-related complications.ResultsRopivacaine (n = 15) infusion significantly reduced pain compared with saline (n = 15) infusion (P < 0.001). For example, the average pain with movement (scale, 0-10) on postoperative day 1 was 6.1 +/- 2.3 for the saline group versus 2.5 +/- 1.6 for the ropivacaine group (P < 0.001). Oral narcotic use and related side effects were significantly decreased in the ropivacaine group. For example, on postoperative day 1, mean tablet consumption was 5.5 +/- 2.4 and 1.7 +/- 1.6 for the saline and ropivacaine groups, respectively (P < 0.001). Sleep disturbance scores were 10-fold greater for saline administration than for ropivacaine infusion (P < 0.001). Overall satisfaction was significantly greater in the ropivacaine group. No catheter- or local anesthetic-related complications occurred.ConclusionAfter moderately painful orthopedic surgery of the upper extremity, ropivacaine infusion using a portable, mechanical pump and an infraclavicular brachial plexus perineural catheter at home decreased pain, sleep disturbances, narcotic use and related side effects, and improved overall satisfaction

Ambulatory perineural infusion: the patients' perspective.
BACKGROUND AND OBJECTIVES:Ambulatory perineural local anesthetic infusion is a relatively new method for providing postoperative analgesia, and many aspects of this technique remain in the domain of conjecture and speculation. This retrospective chart review and survey was undertaken to investigate patients' opinions on various aspects of their ambulatory perineural infusion experience. METHODS:Patients who had received an ambulatory perineural infusion from the University of Florida were identified via pharmacy records. Patients were contacted by phone and were asked various questions regarding their experiences and preferences during and after their perineural infusion. RESULTS:Of 217 patients identified, 215 charts were located and retrieved. Of these, 137 (64%) were successfully contacted and 131 (61%) consented to take part in the survey. More than 97% of patients reported that they felt "safe" during home infusion, that one physician telephone call each night was optimal contact, and that they were comfortable removing the catheter with instructions given over the phone. Only 4% would have preferred to return for catheter removal, and 43% felt that they would have been comfortable with only written instructions for catheter removal. CONCLUSION:This investigation suggests that perineural local anesthetic infusion is generally well tolerated by ambulatory patients

Continuous popliteal sciatic nerve block for postoperative pain control at home: a randomized, double-blinded, placebo-controlled study.
BackgroundThis randomized, double-blinded, placebo-controlled study investigated the efficacy of patient-controlled regional analgesia using a sciatic perineural catheter in the popliteal fossa and a portable infusion pump for outpatients having moderately painful, lower extremity orthopedic surgery.MethodsPreoperatively, patients (n = 30) received a sciatic nerve block and perineural catheter in the popliteal fossa. Postoperatively, patients were discharged with both oral opioids and a portable infusion pump delivering study solution (0.2% ropivacaine or 0.9% saline) via the catheter for 3 days. Investigators and patients were blinded to random group assignment. Daily end-points included pain scores, opioid use and side effects, sleep quality, and symptoms of catheter- or local anesthetic-related complications.ResultsRopivacaine (n = 15) infusion significantly reduced pain compared with saline (n = 15) infusion ( < 0.001). For example, the average pain at rest (scale: 0-10) on postoperative day 1 (median, 25th -75th percentile) was 4.0 (3.5-5.5) for the saline group, versus 0.0 (0.0-0.0) for the ropivacaine group (P < 0.001). Oral opioid use and related side effects were significantly decreased in the ropivacaine group. For example, on postoperative day 1, median tablet consumption was 8.0 (5.0-10.0) and 0.0 (0.0-0.0) for the saline and ropivacaine groups, respectively (P < 0.001). Sleep disturbance scores were more than 10-fold greater for saline administration than for ropivacaine infusion (P < 0.001). Overall satisfaction was significantly greater in the ropivacaine group. Other than two inadvertent catheter dislodgements, no catheter- or local anesthetic-related complications occurred.ConclusionsAfter moderately painful orthopedic surgery of the lower extremity, ropivacaine infusion using a portable mechanical pump and a popliteal sciatic perineural catheter at home decreased pain, opioid use and related side effects, sleep disturbances, and improved overall satisfaction
