RESUMO

OBJECTIVE: Our objective was to evaluate the efficacy of perioperative multimodal pain management in reducing opioid use after elective cesarean delivery (CD). STUDY DESIGN: A single-center, double-blinded, placebo-controlled randomized trial of women undergoing elective CD. Participants were allocated 1:1 to receive the multimodal protocol or matching placebos. The multimodal protocol consisted of a preoperative dose of intravenous acetaminophen, preincision injection of subcutaneous bupivacaine, and intraoperative injection of intramuscular ketorolac. Primary outcome was total opioid intake at 48 hours postoperatively. Secondary outcomes were pain scores, time to first opioid intake, neonatal outcomes, and total outpatient opioid intake on postoperative day (POD) 7. Data were analyzed using parametric and nonparametric tests and quantile regression as appropriate. RESULTS: A total of 242 women were screened with 120 randomized, 60 to the multimodal group and 60 to control group. There was no significant difference in the primary outcome of opioid use nor in the secondary outcomes. Smokers and patients with a history of drug use had higher median postoperative opiate use and earlier administration. On POD 7, only 40% of prescribed opioids had been used, and there was no difference between the groups. CONCLUSION: This perioperative multimodal pain regimen did not reduce opioid use in 48 hours after CD. Patients who smoke or with a history of drug use required more opioids in the postoperative period. Providers significantly overprescribed opioids after CD.

RESUMO

OBJECTIVE: The anatomical landmarks method is currently the most widely used technique for epidural needle insertion and is faced with multiple difficulties in certain patient populations. Real-time ultrasound guidance has been recently used to aid in epidural needle insertion, with promising results. Our aim was to test the feasibility, success rate, and satisfaction associated with a novel real-time ultrasound-guided lumbar epidural needle insertion in the transverse interlaminar view. DESIGN: Prospective descriptive trial on a novel approach. SETTING: Operating room and preoperative holding area at a tertiary care hospital. SUBJECTS: Adult patients presenting for elective open prostatectomy and planned for surgical epidural anesthesia. METHODS: Consented adult patients aged 30-80 years scheduled for open prostatectomy under epidural anesthesia were enrolled. Exclusion criteria included allergy to local anesthetics, infection at the needle insertion site, coagulopathy, and patient refusal. A curvilinear low-frequency (2-5 MHz) ultrasound probe and echogenic 17-G Tuohy needles were used by one of three attending anesthesiologists. Feasibility of epidural insertion was defined as a 90% success rate within 10 minutes. RESULTS: Twenty-two patients were enrolled into the trial, 14 (63.6%) of whom found the process to be satisfactory or very satisfactory. The median time to perform the block was around 4.5 minutes, with an estimated success rate of 95%. No complications related to the epidural block were observed over the 48 hours after the procedure. CONCLUSIONS: We demonstrate the feasibility of a novel real-time ultrasound-guided epidural with transverse interlaminar view.

RESUMO

STUDY OBJECTIVE: Intravenous patient-controlled opioid analgesia (IVPCA), epidural analgesia and transversus abdominis plane (TAP) infiltrations are frequently used postoperative pain management modalities. The aim of this study was to conduct a cost-effectiveness analysis comparing the use of epidural, IVPCA, and TAP infiltrations with liposomal bupivacaine for analgesia in the first 72 h postoperatively in patients undergoing major lower abdominal surgery. DESIGN: Retrospective cost effectiveness analysis. SETTING: Operating room. PATIENTS: We obtained data on major lower-abdominal surgeries performed under general anesthesia on adult patients between January 2012 and July 2014. INTERVENTIONS: A cost-effectiveness analysis was comparing the use of epidural, IVPCA, and TAP infiltrations with liposomal bupivacaine for analgesia in the first 72 h postoperatively. MEASUREMENTS: A decision analytic model was used to estimate the health outcomes for patients undergoing major lower abdominal surgery. The primary outcome was time-weighted pain from 0 to 72 h after surgery, as measured by numerical rating scale pain scores. The analysis was conducted from the perspective of the hospital as the party responsible for most costs related to surgery. MAIN RESULTS: From the base case analysis, IVPCA was the optimal strategy regarding cost and effect. TAP with LB, however, was only narrowly dominated, while epidural was clearly dominated. From the sensitivity analysis at willingness-to-pay (WTP) of $150, IV PCA and TAP infiltration were each the optimal strategy for approximately 50% of the iterations. At WTP of $10,000, epidural was only the optimal strategy in 10% of the iterations. CONCLUSIONS: This is the first study in the literature to compare the cost-effectiveness of epidural, IVPCA, and TAP infiltrations with LB. Within reasonable WTP values, there is little differentiation in cost-effectiveness between IVPCA and TAP infiltration with LB. Epidural does not become a cost-effective strategy even at much higher WTP values.

RESUMO

PURPOSE: We aimed to evaluate the association between preoperative and postoperative neutrophil-to-lymphocyte ratio (NLR) and 30-day postoperative complications after colorectal surgery. METHODS: Patients undergoing elective colorectal surgery between January, 2010 and December, 2014 were identified. Patients who had preoperative and postoperative days 1 and 2 (Postoperative day [POD]-1, POD-2) NLR were included in the study. Primary study outcomes were optimal NLR cutoff values at preop, POD-1, and POD-2. RESULTS: A total of 1328 patients met the inclusion criteria. Of those, 518 (39%) patients experienced at least one postoperative complication. Sex (P<0.001), diabetes mellitus (DM) (P<0.001), diagnosis (P=0.001), operation type (P=0.03), and open surgery (P<0.001) were statistically associated with higher NLR (POD-1, P=0.02; POD2, P=0.01). DM (OR, 1.97; 95%CI, 1.27-3.08; P=0.003] and NLR on POD-2≥9.2 (OR, 1.43; 95%CI, 1.03-1.98; P=0.02) were significantly related to postoperative complications. CONCLUSIONS: NLR may provide clinicians with an additional tool for identifying patients at high risk for postoperative complications after elective colorectal surgery. Routine use of NLR may lead to early intervention and potentially improve the management of complications after colorectal surgery.

RESUMO

STUDY OBJECTIVE: The primary aim of the proposed study was to determine the association between postoperative pain and breastfeeding after cesarean delivery during hospital stay. DESIGN: Retrospective cohort study. SETTING: Postoperative recovery area and operating room. PATIENTS: Data was obtained on singleton pregnancies undergoing scheduled cesarean deliveries under spinal anesthesia between 2013 and 2016. INTERVENTIONS: Determine the association between postoperative pain and breastfeeding after cesarean delivery. MEASUREMENTS: Postoperative pain score, breastfeeding, LATCH score post-partum depression and length of stay values collected. MAIN RESULTS: The dataset consisted of electronic medical records from 5350 patients. We found that the pain score is negatively associated with the LATCH score; higher pain was associated with lower LATCH scores, -0.01 [-0.01,-0.00], p < .0402. Every one-point increase in average pain score was associated with a 21% reduction in the odds of in-hospital exclusive breast-feeding relative to exclusive formula-feeding, OR = 0.79 [0.70-0.90], p < .0002. We observed that the post-partum depression status was associated with the average postoperative pain score, F (1, 5347) = 41.51, p < .0001. We also found a significant positive association between the average pain score and the duration of hospital stay (p < .0001); every one-point increase in the average pain-score was associated with a 7.98 [6.28, 9.68] hour increase in length of stay. CONCLUSIONS: Our results demonstrate significant association between the increase in post-cesarean pain scores and deterioration of breastfeeding initiation while also exposing slight reductions in the quality of breastfeeding. Additionally, we found that increases in post-cesarean pain scores also positively associate with postpartum depression and duration of stay, with each increase in pain score resulted in an almost one-day increase in the length of stay.

RESUMO

BACKGROUND: Hypotension compromises local tissue perfusion, thereby reducing tissue oxygenation. Hypotension might thus be expected to promote infection. Hypotension on surgical wards, while usually less severe than intraoperative hypotension, is common and often prolonged. In this retrospective cohort study, we tested the hypotheses that there is an association between surgical site infections and low postoperative time-weighted average mean arterial pressure and/or postoperative minimum mean arterial pressure. METHODS: We considered patients who had colorectal surgery lasting ≥1 hour at the Cleveland Clinic between 2009 and 2013. We defined blood pressure exposures as time-weighted average (primary) and minimum mean arterial pressure (secondary) within 72 hours after surgery. We assessed associations between continuous blood pressure exposures with a composite of deep and superficial surgical site infection using separate severity-weighted average relative effect generalized estimating equations models, each using an unstructured correlation structure and adjusting for potentially confounding variables. RESULTS: A total of 5896 patients were eligible for analysis. Time-weighted mean arterial pressure and surgical site infection were not significantly associated, with an estimated odds ratio (95% CI) of 1.03 (0.99-1.08) for a 5-mm Hg decrease (P = .16). However, there was a significant inverse association between minimum postoperative mean arterial pressure and infection, with an estimated odds ratio of 1.08 (1.03-1.12) per 5-mm Hg decrease (P = .001). CONCLUSIONS: Postoperative time-weighted mean arterial pressure was not associated with surgical site infection, but lowest postoperative mean arterial pressure was. Whether the relationship is causal remains to be determined.

RESUMO

BACKGROUND: Various methods for peripheral nerve and epidural catheter location assessment exist, with varying degrees of ease of use, utility, and accuracy. Pulsed wave Doppler (PWD) evaluates the presence of fluid flow and is possible modality to assess the location of a percutaneously inserted perineural catheter. METHODS: A retrospective chart review was conducted in which PWD ultrasonography was used to confirm the position of nerve catheters for regional anesthesia. Data was collected to assess 24-hour postoperative pain scores, opioid consumption, complications, and the incidence of catheter replacement. RESULTS: Eighty-six patients were included; average age was 58 years and a 27% incidence of chronic pain. These catheters were left in place based on the PWD images. Three catheters failed and a total of 16 catheters were repositioned. In the first 24 hours average pain scores ranges between 3.5 to 5.9 and median postoperative opioid consumption range was 11.3 mg to 60.8 mg. For epidural catheters, PWD changes were more obvious with air injection and there was only one episode of hemodynamic instability. CONCLUSIONS: Our preliminary experience with PWD ultrasonography suggests that they may offer the ability to selectively assess flow at different locations to identify the proper location of epidural and perineural catheters. Future randomized, controlled investigations are warranted to further evaluate the effectiveness and safety of this modality.

RESUMO

In the gluteal and thigh region, the arteria comitans accompanies the sciatic nerve for a short distance, then penetrates the nerve and runs to the lower part of the thigh. There is no study that recognizes this artery as a guide to the location of the sciatic nerve. In this report, we describe a series of 6 knee arthroplasty patients in whom ultrasound-guided sciatic nerve block was successfully performed using color Doppler and pulsed wave Doppler to visualize the arteria comitans as a guide to the location of the sciatic nerve. We have found that detecting the arteria comitans as a landmark is novel and may offer an additional tool with the existing methods for sciatic nerve block.

RESUMO

Currently, no gold standard method exists for localization of an epidural catheter after placement. The technique described in this report uses pulsed-wave Doppler (PWD) ultrasound to identify intrathecal location of an epidural catheter. A thoracic epidural catheter was inserted after multiple trials with inconclusive aspiration and test dose. Ultrasound PWD confirmed no flow in the epidural space and positive flow in the intrathecal space. A fluid aspirate was positive for glucose, reconfirming intrathecal placement. PWD is a potential tool that can be used to locate the tip of an epidural catheter.

RESUMO

BACKGROUND: Dexmedetomidine is increasingly used in children undergoing cardiac catheterization procedures. We compared the percentage of surgical time with hemodynamic instability and the incidence of postoperative agitation between pediatric cardiac catheterization patients who received dexmedetomidine infusion and those who did not and the incidence of postoperative agitation. MATERIALS AND METHODS: We matched 653 pediatric patients scheduled for cardiac catheterization. Two separate multivariable linear mixed models were used to assess the association between dexmedetomidine use and intraoperative blood pressure and heart rate instability. A multivariate logistic regression was used for relationship between dexmedetomidine and postoperative agitation. RESULTS: No difference between the study groups was found in the duration of MAP ( P = .867) or heart rate (HR) instabilities ( P = .224). The relationship between dexmedetomidine use and the duration of negative hemodynamic effects does not depend on any of the considered CHD types (all P > .001) or intervention ( P = .453 for MAP and P = .023 for HR). No difference in postoperative agitation was found between the study groups ( P = .590). CONCLUSION: Our study demonstrated no benefit in using dexmedetomidine infusion compared with other general anesthesia techniques to maintain hemodynamic stability or decrease agitation in pediatric patients undergoing cardiac catheterization procedures.

RESUMO

BACKGROUND: Women have blamed epidurals for their post-partum back pain for decades. Survey-based studies have shown similar incidence of chronic back pain between women who delivered with epidurals compared to those who did not. However, epidural insertion site pain has yet to be evaluated by a quantitative measure: pressure pain threshold (PPT). Algometer measured PPT has been shown to be accurate and reproducible in acute, chronic, and postoperative pain studies. This study determines the effect of ultrasound-based landmarks on the PPT at the epidural insertion site in the post-partum period. METHODS: Participants were randomized into either the ultrasound or sham groups. In addition, a non-randomized control group (no epidural) participated. Ultrasound of the lumbar region was used to mark mid intervertebral levels in the US group but not in the sham group. Epidural were placed using the marks in the US group or palpated bony landmarks in the sham group. PPT at each intervertebral space measured before and after the use of epidural. RESULTS: Epidural placement did significantly decreased PPT in US (68%) and US sham (79%) groups and less in the control group (21%). US group showed decreased PPT only at insertion site whereas US sham group also showed decreased PPT at insertion site and adjacent levels. CONCLUSIONS: We showed that epidural placed with ultrasound-determined landmarks not only improves the success of epidural placement but also minimizes the number of intervertebral levels with decreased PPT.

RESUMO

OBJECTIVE: International scientific publication productivity is a tangible indicator for the accuracy of scientific policies. The quality of scientific publications is not increasing despite the fast increase in the publication count in Turkey. The international publication activities of Turkish anaesthesia clinics have not been previously explored. Thus, we aimed to evaluate the high quality scientific productivity of Turkish anesthesia clinics within the last 10 years. METHODS: We searched for studies conducted by anaesthesiologists in Turkey within the last 10 years and published in journals listed under the medical subject categories of anaesthesiology and critical care using 'Thomson Reuters InCites' and PubMed databases. We recorded publication year, subject, method, citation count and origin of each paper and conducted descriptive analyses. RESULTS: There were 630 papers meeting our inclusion criteria. Among those, 525 (83%) were studies on anaesthesia, 66 (10%) were studies on critical care and 39 (6%) were studies on pain. The average citation count was 9.90. There were 376 controlled/randomized controlled trials, 98 observational studies, 66 laboratory studies, 64 case series/reports, 5 reviews and 21 letters to the editor. Studies were conducted by universities (82.4%), by training and research hospitals (15.56%), by state and military hospitals (0.63%) and by physicians in private practice (1.27%). Baskent University had the highest publication count, Istanbul University had the highest citation count and Trakya University had the highest publication count per faculty teaching staff. CONCLUSION: The high-impact scientific productivity of Turkish anesthesia clinics is in a downward trend in the last 10 years, and the average citation count is lower than the global average.

RESUMO

BACKGROUND: Systemic lupus erythematosus (SLE) is a common autoimmune connective tissue disease that mainly harms kidneys, heart, lungs, and nervous system. Effects of surgical stimulus and anesthesia combined with SLE-related pathologies may increase morbidity and mortality. Therefore, we aimed to evaluate the association between SLE (versus none) and postoperative renal, cardiac, and in-hospital mortality complications among patients undergoing major surgeries. METHODS: We obtained censuses of 2009 to 2011 inpatient hospital discharges across 7 states and conducted a retrospective cohort study by using International Classification of Diseases and Injuries, Version 9, diagnosis codes, procedure codes, and present-on-admission indicators. We included patients who had major surgery and matched each SLE discharge up to 4 control discharges for potential confounders. We assessed the association between matched SLE patients and controls on in-hospital renal complications, cardiovascular complications, and in-hospital mortality using separate logistic regression models. RESULTS: Among 8 million qualifying discharges, our sample contained 28,269 SLE patients matched with 13,269 controls. SLE was associated with a significantly higher risk of postoperative renal complications, with an estimated odds ratio (99% CI) of 1.33 (1.21, 1.46); P < .001. In addition, SLE was significantly associated with a higher risk of in-hospital mortality, with an estimated odds ratio (99% CI) of 1.27 (1.11, 1.47); P < .001. However, we found no significant association between SLE and cardiac complications, with an estimated odds ratio (99% CI) of 0.98 (0.83, 1.16), P = .79. CONCLUSIONS: This is, by far, the largest clinical study for postoperative outcomes of SLE patients with adequately powered statistical analyses. We concluded that SLE was associated with a higher risk of renal complications and in-hospital mortality but not cardiac events after major surgery. In SLE patients, more aggressive measures should be taken to prevent renal injury in the perioperative period.

RESUMO

BACKGROUND: There are limited reports of lumbar neuraxial blocks using real-time US in patients with predicted difficulties. We compared the number of attempts to perform spinal anesthesia using real-time US guidance versus landmark technique in patients meeting predefined criteria for difficult spinal anesthesia. We also compared procedure time, block success, patient satisfaction and difficulty scores between groups. METHODS: Following institutional review board approval patients scheduled for total hip or knee arthroplasty with expected difficulty to perform spinal anesthesia were included. Number of attempts, block time, success rate, patient satisfaction and difficulty scores were recorded and we conducted the Kruskal-Wallis non-parametric test of difference between the groups. RESULTS: Thirty-eight patients were enrolled and a total of 32 data sets was analyzed. For number of attempts, we observed no difference between the groups (P<0.83). The US group resulted in marginally higher time to block compared to the control (P<0.0653). The US group resulted in marginally higher satisfaction compared to the control group (P<0.09). The block success rate was 100% in both groups. Anesthesiologists rated the US group procedure more difficult than the control group (χ2=10.85, P<0.0010). CONCLUSIONS: This trial suggests that real-time US guidance for spinal anesthesia in challenging patients in comparison to the controlled group was completed in longer time, with lower needle insertion attempts, and higher patient satisfaction scores but without statistically significant differences.

RESUMO

BACKGROUND: Ultrasound-guided nerve blocks have become the standard when performing regional nerve blocks in anaesthesia. Infiniti Plus (CIVCO Medical Solutions, Kalona, Iowa, USA) is a needle guide that has been recently developed to help clinicians in performing ultrasound-guided nerve blocks. OBJECTIVES: We tested the hypothesis that femoral nerve catheter placement carried out with the Infiniti Plus needle guide will be quicker to perform than without the Infiniti Plus. Secondary aims were to assess whether the Infiniti Plus needle guide decreased the number of block attempts and also whether it improved needle visibility. DESIGN: A randomised, controlled trial. SETTING: Cleveland Clinic, Cleveland, Ohio, USA. PATIENTS: We enrolled adult patients having elective total knee arthroplasty with a femoral nerve block and femoral nerve catheter. Patients, who were pregnant or those who had preexisting neuropathy involving the surgical limb, coagulopathy, infection at the block site or allergy to local anaesthetics were excluded. INTERVENTIONS: Patients were randomised into two groups to receive the ultrasound-guided femoral nerve catheter placement with or without the Infiniti Plus needle guide. MAIN OUTCOME MEASURES: The time taken to place the femoral nerve catheter, the number of attempts, the success rate and needle visibility were recorded. We used an overall α of 0.05 for both the primary and secondary analyses; the secondary analyses were Bonferroni corrected to control for multiple comparisons. RESULT: The median (interquartile range Q1 to Q3) time to perform the femoral nerve catheter placement was 118 (100 to 150) s with Infiniti Plus and 177 (130 to 236) s without Infiniti Plus. Infiniti Plus significantly reduced the time spent performing femoral nerve catheterisation, with estimated ratio of means [(95% confidence interval), P value] of 0.67 [(0.60 to 0.75), P < 0.001] with Infiniti Plus compared with no Infiniti Plus. However, Infiniti Plus had no effect on the odds of a successful femoral nerve catheter placement, number of attempts or percentage of perfect needle visibility. CONCLUSION: We found that the use of Infiniti Plus decreased the median time to successfully place a femoral nerve catheter by 33% compared with not using Infiniti Plus. This difference may be more apparent to clinicians undertaking this procedure less often or by those in training as our team was very experienced, had been trained in the technique and was working in a hospital with a large caseload.

RESUMO

INTRODUCTION: Intravenous patient-controlled opioid analgesia has been an important improvement in addressing insufficient management of acute postoperative pain for over 40 years. However, there are number of weaknesses for intravenous patient-controlled analgesia, including operator and device error, intravenous line patency issues, and risk of catheter-related infection, all of which contribute to the complications and increase in cost of care. The sublingual sufentanil tablet system is a major evolution in both drug and technological management of postoperative pain. Areas covered: We reviewed the use of the sublingual sufentanil tablet system in management of moderate to severe postoperative pain in hospitalized patients, with a particular focus on the pharmacological properties of sufentanil and clinical use in different surgical patients. Expert opinion: The sublingual sufentanil tablet system can decrease intravenous opioid based patient-controlled analgesia related complications and safety issues. Current clinical studies have demonstrated this noninvasive-novel system to be safe and effective in management of acute pain in the postsurgical setting. Researchers should focus on comparing it with other available patient controlled analgesia modalities and evaluating the efficiency and cost effectiveness of the sublingual sufentanil tablet system.
