The 30-day mortality rate was 0.7% (n = 4) for normocapnia, 1.5% (n = 4) for hypocapnia, 2.2% (n = 3) for hypercapnia, and 7.5% (n = 4) for the dual-exposure group. The extubation times were 13.3±21.7 hours, 15.8±21.37 hours, 21.79±39.70 hours, and 42.29±75.35 hours, respectively. After adjusting for confounding variables, the dual hypocapnia and hypercapnia exposure group was associated with increased 30-day mortality (odds ratio [OR] = 8.08; 95% confidence interval [CI], 1.82-35.86; p = 0.006) and delayed extubation (OR = 2.40; 95% CI, 1.24-4.64; p = 0.010).\u0000\u0000\u0000CONCLUSIONS\u0000Exposure to both hypocapnia and hypercapnia within 24 hours after CABG was associated independently with increased risk of 30-day mortality and delayed extubation.

Recovery from NMB and restoration of full control of pharyngeal and laryngeal muscles are important in airway maintenance and protection in surgical patients. Neuromuscular block can be accurately monitored using acceleromyography. Sugammadex, the first of a new class of selective muscle relaxant–binding drugs, is used to rapidly and effectively reverse NMB induced by aminosteroid neuromuscular-blocking drugs. Studies have looked at NMB reversal on various muscles, none of which correlate exactly with recovery of laryngeal muscles. An observational study was carried out to evaluate the efficacy of sugammadex in reversing rocuronium-induced NMB of laryngeal muscle function using neurophysiologic monitoring. Another aim of this study was to establish the time of recovery after 16 mg/kg of sugammadex using motor-evoked potentials (MEPs) compared with acceleromyography. All statistical tests were 2-sided with a significance level of 0.05, and the results were presented as the mean (continuous variables) ± SD or percentage (categorical variables). The test results showed that myogenicMEPs responses were absent, and neuromuscular monitoring showed a deep block in all patients (train-of-4 ratio of 0, posttetanic count of 1–2) at the time of sugammadex administration. It was also observed that the time to complete recovery of the basal myogenic MEPs amplitudes was 70 ± 18.2 at the laryngeal adductor muscles and 135 ± 14.1 seconds at the abductor digiti minimi. The value of the corresponding train-of-4 ratio was 0.7 ± 0.1. Incomplete neuromuscular recovery can cause respiratory impairment and hypoxemia in patients; hence, complete recovery of neuromuscular transmission at the laryngeal muscles is paramount for airway protection. This neurophysiologic study confirmed that administering 16 mg/kg sugammadex caused complete and effective recovery of laryngeal nerve function from rocuroniuminduced NMB. No adverse effects due to transcutaneous stimulation (such as cardiac arrhythmias and skin irritation) of the laryngeal nerve were observed, and no adverse effects due to sugammadex were noted.","PeriodicalId":22104,"journal":{"name":"Survey of Anesthesiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75330414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This prospective randomized study aimed at examining the hemodynamic consequences of manual and portable ventilation during transport from the operating room (OR) to the intensive care unit (ICU) in intubated patients following cardiac surgery. The study also hypothesized that manual ventilation after cardiac surgery would result in greater changes in measured end-tidal carbon dioxide (ETCO2) and pulmonary artery (PA) pressure when compared to machine ventilation. The study data were composed of 36 cardiac surgery patients with planned intubation during transport to the ICU. Following surgery, the patients were randomized into 2 cohorts to receive either manual ventilation (with a self-inflating bag-valve resuscitator) or machine ventilation (attached to a portable transport ventilator) during in-hospital transport. Hand ventilation was done by the anesthesiologist who provided care during surgery, and machine ventilation was set by a respiratory therapist to match parameters in the OR at the end of the case. Hemodynamic variables, ETCO2, and PA pressures before and during transport and upon arrival in the ICU were recorded. A 2-sided, unpaired t test was used to determine differences between values, and a threshold P < 0.05 was considered statistically significant. The 3 study outcomes measured were the difference from baseline ETCO2, hemodynamic changes from baseline, and changes in PA pressure before and after transport. There was no difference in transport time between hand-ventilated (mean, 5 ± 1.41 minutes) and machine-ventilated (mean, 5.47 ± 1.74 minutes) patients (P = 0.369). The transport ETCO2 excursion was significantly different between hand-ventilated (5.44) and machineventilated patients (2.32, P = 0.0126), but the total ETCO2 excursion was not significant (P = 0.066). These differences were not associated with a difference inmean PA pressure. No differences were found in mean arterial pressure, heart rate, or SpO2 (ICU vs OR). In conclusion, manual ventilation was associated with greater changes from baseline ETCO2 than machine ventilation during transport after cardiac surgery, but these differences were not associated with changes in mean PA pressure, vital signs, oxygen saturation, or heart rhythm upon arrival at ICU. The results do not support routine use of a transport ventilator in patients transported after cardiac surgery.","PeriodicalId":22104,"journal":{"name":"Survey of Anesthesiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80007527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this retrospective analysis was to evaluate the reliability and efficacy of ProPlege and EndoVent catheters, commonly referred to as “necklines,” for intraoperative CS cardioplegia and pulmonary artery venting in the setting of MIAVR. The study evaluated the records of 51patients who underwent MIAVR either through upper hemisternotomy or right anterior thoracotomy. The ProPlege device was placed into the CS under transesophageal echocardiography and pressure guidance, and the EndoVent device was placed using pressure-curve monitoring by the anesthesiologist prior to the surgical procedure. Minimally invasive cardiac surgery for aortic valve replacement was performed through a J-shaped upper hemisternotomy in 38 patients and a right anterior thoracotomy in 13 patients. Line performance, time needed for placement, rate of successful placement, and major perioperative complications were recorded and reviewed. Necklines were placed successfully in all patients, and the mean time for the placement was 14 ± 9 minutes for ProPlege and 9 ± 4 minutes for EndoVent. A total of 110 doses of retrograde cardioplegiawere delivered through the ProPlege device at a mean flow rate of 173±35mL/min and amean pressure of 41±6mmHg. Venting of the heart by the pulmonary catheter grading was “excellent” in 33 patients, “sufficient” in 12 patients, and “not adequate” in 2 patients. Thesewere surgeon-reported scores based on satisfaction in the degree of freedom from blood in the field. Results showed no deaths or complications, including perioperative myocardial infarction, postoperative re-exploration for bleeding, stroke, kidney failure, or low-output syndrome. In conclusion, ProPlege devices and EndoVent catheters were found to be reliable and ensured effective CS cardioplegia and pulmonary artery venting in the setting of MIAVR. The necklines provided adequate myocardial protection, acceptable grade of venting of the heart, and unobstructed vision and access during MIAVR procedures. Further research is required to demonstrate the advantages of necklines over conventional techniques.","PeriodicalId":22104,"journal":{"name":"Survey of Anesthesiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90040899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
