Background Patients with congenital heart disease (CHD) and heterotaxy show high postsurgical morbidity/mortality, with some developing respiratory complications. Although this finding is often attributed to the CHD, airway clearance and left-right patterning both require motile cilia function. Thus, airway ciliary dysfunction (CD) similar to that of primary ciliary dyskinesia (PCD) may contribute to increased respiratory complications in heterotaxy patients. Methods and Results We assessed 43 CHD patients with heterotaxy for airway CD. Videomicrocopy was used to examine ciliary motion in nasal tissue, and nasal nitric oxide (nNO) was measured; nNO level is typically low with PCD. Eighteen patients exhibited CD characterized by abnormal ciliary motion and nNO levels below or near the PCD cutoff values. Patients with CD aged >6 years show increased respiratory symptoms similar to those seen in PCD. Sequencing of all 14 known PCD genes in 13 heterotaxy patients with CD, 12 without CD, 10 PCD disease controls, and 13 healthy controls yielded 0.769, 0.417, 1.0, and 0.077 novel variants per patient, respectively. One heterotaxy patient with CD had the PCD causing DNAI1 founder mutation. Another with hyperkinetic ciliary beat had 2 mutations in DNAH11, the only PCD gene known to cause hyperkinetic beat. Among PCD patients, 2 had known PCD causing CCDC39 and CCDC40 mutations. Conclusions Our studies show that CHD patients with heterotaxy have substantial risk for CD and increased respiratory disease. Heterotaxy patients with CD were enriched for mutations in PCD genes. Future studies are needed to assess the potential benefit of prescreening and prophylactically treating heterotaxy patients for CD.

This proof of concept study demonstrates that percutaneous femoral nerve stimulation is feasible for ambulatory knee surgery; and suggests that this modality may be effective in providing analgesia and decreasing opioid requirements following anterior cruciate ligament reconstruction. clinicaltrials.gov: NCT02898103.

BackgroundParavertebral nerve blocks (PVBs) are frequently used to treat pain during and following breast surgery, but have various undesirable risks such as pneumothorax. The erector spinae plane block (ESPB) also provides perioperative breast analgesia, but is purported to be easier to administer with a favorable safety profile. However, it remains unknown if the new ESPB provides comparable analgesia as the decades-old PVB technique.MethodsSubjects undergoing unilateral or bilateral non-mastectomy breast surgery were randomized to a single-injection ESPB or PVB in a subject-blinded fashion (ropivacaine 0.5% with epinephrine; 20 mL unilateral or 16 mL/side for bilateral). We hypothesized that (1) analgesia would be non-inferior in the recovery room as measured on a Numeric Rating Scale (NRS) with ESPB, and (2) opioid consumption would be non-inferior in the operating and recovery rooms with ESPB.ResultsBoth pain scores and opioid consumption were higher in subjects with ESPBs (n=50) than PVBs (n=50; median NRS 3.0 vs 0; 95% CI −3.0 to 0; p=0.0011; and median morphine equivalents 2.0 vs 1.5 mg; 95% CI −1.2 to −0.1; p=0.0043). No block-related adverse events occurred in either group.ConclusionsPVBs provided superior analgesia and reduced opioid requirements following non-mastectomy breast surgery. To compare the relatively rare complications between the techniques will require a sample size 1–2 orders of magnitude greater than the current investigation; however, without a dramatic improvement in safety profile for ESPBs, it appears that PVBs are superior to ESPBs for postoperative analgesia after non-mastectomy breast surgery.Trial registration numberNCT03549234.

Background and objectivesPercutaneous peripheral nerve stimulation (PNS) is an analgesic modality involving the insertion of a lead through an introducing needle followed by the delivery of electric current. This modality has been reported to treat chronic pain as well as postoperative pain following knee and foot surgery. However, it remains unknown if this analgesic technique may be used in ambulatory patients following upper extremity surgery. The purpose of this proof-of-concept study was to investigate various lead implantation locations and evaluate the feasibility of using percutaneous brachial plexus PNS to treat surgical pain following ambulatory rotator cuff repair in the immediate postoperative period.MethodsPreoperatively, an electrical lead (SPR Therapeutics, Cleveland, Ohio) was percutaneously implanted to target the suprascapular nerve or brachial plexus roots or trunks using ultrasound guidance. Postoperatively, subjects received 5 min of either stimulation or sham in a randomized, double-masked fashion followed by a 5 min crossover period, and then continuous stimulation until lead removal postoperative days 14–28.ResultsLeads (n=2) implanted at the suprascapular notch did not appear to provide analgesia, and subsequent leads (n=14) were inserted through the middle scalene muscle and placed to target the brachial plexus. Three subjects withdrew prior to data collection. Within the recovery room, stimulation did not decrease pain scores during the first 40 min of the remaining subjects with brachial plexus leads, regardless of which treatment subjects were randomized to initially. Seven of these 11 subjects required a single-injection interscalene nerve block for rescue analgesia prior to discharge. However, subsequent average resting and dynamic pain scores postoperative days 1–14 had a median of 1 or less on the Numeric Rating Scale, and opioid requirements averaged less than 1 tablet daily with active stimulation. Two leads dislodged during use and four fractured on withdrawal, but no infections, nerve injuries, or adverse sequelae were reported.ConclusionsThis proof-of-concept study demonstrates that ultrasound-guided percutaneous PNS of the brachial plexus is feasible for ambulatory shoulder surgery, and although analgesia immediately following surgery does not appear to be as potent as local anesthetic-based peripheral nerve blocks, the study suggests that this modality may provide analgesia and decrease opioid requirements in the days following rotator cuff repair. Therefore, it suggests that a subsequent, large, randomized clinical trial with an adequate control group is warranted to further investigate this therapy in the management of surgical pain in the immediate postoperative period. However, multiple technical issues remain to be resolved, such as the optimal lead location, insertion technique, and stimulating protocol, as well as preventing lead dislodgment and fracture.Trial registration number NCT02898103.

Introduction: There are various important implications associated with poorly controlled postoperative pain in the adult surgical patientthis includes cardiopulmonary complications, opioid-related side effects, unplanned hospital admissions, prolonged hospital stay, and the subsequent development of chronic pain or opioid addiction. With the ongoing national opioid crisis, it is imperative that perioperative providers implement pathways for surgical patients that reduce opioid requirements and painrelated complications. Areas covered: In this review, the authors discuss the components of a multimodal opioid-sparing analgesia pathway as it pertains to the perioperative environment. Medications reviewed include gabapentinoids, acetaminophen, non-steroidal anti-inflammatory drugs, ketamine, intravenous lidocaine, dexmedetomidine, and glucocorticoids. The use of peripheral nerve blocks and neuraxial analgesia are also discussed. Expert opinion: In appropriate cases, regional anesthetic interventions are extremely useful for postoperative analgesia, including peripheral nerve blocks and neuraxial analgesia and while newer postoperative analgesics have been postulated, the literature on such is presently controversial. Coordinated approaches to pain management are recommended to reduce the need for opioids and to improve patient satisfaction post-surgery.

Objective Patients with heterotaxy and complex congenital heart disease (CHD) undergo cardiac surgery with high mortality and morbidity. Recent studies have revealed an association among heterotaxy, CHD, and primary ciliary dyskinesia (PCD). We undertook a retrospective review of patients undergoing cardiac surgery at Children’s National Medical Center between 2004 to 2008 to explore the hypothesis that in heterotaxy patients there is increased mortality and respiratory complications. Methods and Results Retrospective review was performed on post-surgical outcomes of 87 patients with heterotaxy and CHD exhibiting the full spectrum of situs abnormalities associated with heterotaxy. As controls, 634 cardiac surgical patients with CHD but without laterality defects were selected, and surgical complexities were similar with a median RACHS-1 score of 3.0 for both groups. We found the mean length of postoperative hospital stay (17 vs 11 days) and mechanical ventilation (11 vs 4 days) were significantly increased in the heterotaxy patients. Also elevated were rates of tracheostomies (6.9% vs. 1.6%; Odds Ratio 4.6), extracorporeal membrane oxygenation (ECMO) support (12.6% vs. 4.9%: Odds Ratio 2.8), prolonged ventilatory courses (23% vs. 12.3%; Odds Ratio 2.1) and post-surgical deaths (16.1% vs. 4.7%; Odds Ratio 3.9). Conclusions Our findings show heterotaxy patients had more post-surgical events with increased post-surgical mortality and risk for respiratory complications as compared to controls with similar RACHS-1 surgical complexity scores. We speculate that increased respiratory complications maybe due to ciliary dysfunction. Further, studies are needed to explore the basis for the increased surgical risks for heterotaxy patients undergoing cardiac surgery.

Our findings showed that heterotaxy-CHD patients with CD may have increased risks for respiratory deficiencies. Overall, there was a trend toward increased mortality in CD patients with intermediate follow-up evaluation. Because β-agonists are known to increase ciliary beat frequency, presurgical screening for CD and perioperative treatment of CD patients with inhaled β-agonists may improve postoperative outcomes and survival.

Objectives: Invasive fungal rhinosinusitis is a rare, life-threatening condition that affects the paranasal sinuses. The standard of care after diagnosis includes surgical debridement and aggressive medical management. Despite treatment, mortality remains unacceptably high. Most data are derived from small cohort experiences, with limited identification of mortality risk factors in the acute setting. The authors used a large national database to better understand clinical factors associated with inpatient mortality for this challenging condition. Methods: Using the 2000-2014 National (Nationwide) Inpatient Sample database, the authors identified 979 adult patients with an International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code of mucormycosis or aspergillosis and a procedure code of sinus surgery. Multivariate imputation by chained equation was performed to account for missing data, followed by multivariate logistic regression to identify predictors of inpatient mortality. Results: In total, 979 adult patients were identified, with a median age of 57 years. The inpatient mortality rate was 15.8%. The most prevalent comorbidity was hematologic disorders (42.9%). Mucormycosis versus aspergillosis was associated with increased odds of inpatient mortality (odds ratio, 2.95; 95% confidence interval, 2.00-4.34; P < .001). The odds of inpatient mortality were significantly increased between patients with hematologic disorders and those without (odds ratio, 1.92; 95% confidence interval, 1.08-3.39; P = .024). Diabetes (odds ratio, 0.53; 95% confidence interval, 0.34 − 0.80; P = .003) was associated with the lowest odds of inpatient mortality. Conclusions: This represents the first population-based study evaluating the factors associated with inpatient mortality. These findings support prior observations demonstrating that the underlying immune dysfunction and type of fungal infection are important predictors of early mortality.
