Anesthesia for ERCP: Impact of Anesthesiologist's Experience on Outcome and Cost. Anesthesiol Res Pract 2013; 2013:570518. [PMID: 23781243 PMCID: PMC3679699 DOI: 10.1155/2013/570518] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2013] [Revised: 05/01/2013] [Accepted: 05/13/2013] [Indexed: 12/17/2022] Open
Abstract
The present study evaluates the effect of anesthesiologist's experience in providing deep sedation for endoscopic retrograde cholangiopancreatography (ERCP) on cost and safety. Methodology. Perioperative records of 1167 patients who underwent ERCP were divided on the basis of anesthesiologist assisting these procedures either on regular basis (Group R) or on ad hoc basis (Group N). Comparisons were made for anesthesia times, complication rates, and airway interventions. Results. Across all American Society of Anesthesiologists (ASA) Classes, regular anesthesiologists were more efficient (overall mean anesthesia time in Group R was 24.82 ± 12.96 versus 48.63 ± 21.53 minutes in Group N). Within Group R, anesthesia times across all ASA classes were comparable. In Group N, anesthesia times for higher ASA status patients were significantly longer (ASA IV, 64.62 ± 35.78 versus ASA I, 45.88 ± 11.19 minutes). Intubation rates (0.76% versus 12.8%) and median minimal oxygen saturation (100% versus 97.01%) were significantly higher in Group R. Had Group R anesthesiologists performed all procedures, the hospital could have saved US $ 758536 (based upon operating room time costs). Conclusion. Experience in providing deep sedation improved patient safety and decreased the operating room turnaround time, thereby lowering operating room costs associated with these procedures.

Abstract
IMPORTANCE Deep sedation for endoscopic procedures has become an increasingly used option but, because of impairment in patient response, this technique also has the potential for a greater likelihood of adverse events. The incidence of these complications has not been well studied at a population level. DESIGN Population-based study. SETTING AND PARTICIPANTS Using a 5% random sample of cancer-free Medicare beneficiaries who resided in one of the regions served by a SEER (Surveillance, Epidemiology, and End Results) registry, we identified all procedural claims for outpatient colonoscopy without polypectomy from January 1, 2000, through November 30, 2009. INTERVENTION Colonoscopy without polypectomy, with or without the use of deep sedation (identified by a concurrent claim for anesthesia services). MAIN OUTCOME MEASURES The occurrence of hospitalizations for splenic rupture or trauma, colonic perforation, and aspiration pneumonia within 30 days of the colonoscopy. RESULTS We identified a total of 165 527 procedures in 100 359 patients, including 35 128 procedures with anesthesia services (21.2%). Selected postprocedure complications were documented after 284 procedures (0.17%) and included aspiration (n = 173), perforation (n = 101), and splenic injury (n = 12). (Some patients had >1 complication.) Overall complications were more common in cases with anesthesia assistance (0.22% [95% CI, 0.18%-0.27%]) than in others (0.16% [0.14%-0.18%]) (P < .001), as was aspiration (0.14% [0.11%-0.18%] vs 0.10% [0.08%-0.12%], respectively; P = .02). Frequencies of perforation and splenic injury were statistically similar. Other predictors of complications included age greater than 70 years, increasing comorbidity, and performance of the procedure in a hospital setting. In multivariate analysis, use of anesthesia services was associated with an increased complication risk (odds ratio, 1.46 [95% CI, 1.09-1.94]). CONCLUSIONS AND RELEVANCE Although the absolute risk of complications is low, the use of anesthesia services for colonoscopy is associated with a somewhat higher frequency of complications, specifically, aspiration pneumonia. The differences may result in part from uncontrolled confounding, but they may also reflect the impairment of normal patient responses with the use of deep sedation.

Abstract
OBJECTIVE To evaluate PillCam colon capsule endoscopy (PCCE) in detecting the severity and extent of active ulcerative colitis (UC), in comparison with conventional endoscopy. METHODS From July 2009 to June 2012, patients with confirmed UC were enrolled in this prospective single-center study. After they had undergone the PCCE, they received a conventional colonoscopy. The extent of mucosal damage and inflammatory lesions during both procedures was recorded for comparison. In addition, the regimen of bowel preparation, completion rate, colonic cleansing, compliance or adverse events were analyzed. RESULTS A total of 26 patients was consecutively included, among whom one was withdrawn. The remaining 25 (nine females and 16 males with a mean age of 44.2 years) completed the study. There was significant correlation in the severity (κ = 0.751, P < 0.001) and extent (κ = 0.522, P < 0.001) of UC between the PCCE and conventional colonoscopy. In addition, the excellent to good rate of colonic cleanliness in PCCE was 80%. There were no remarkable adverse events during the study. CONCLUSION PCCE provides an outstanding performance in the detection of the severity and extent of active UC.

Abstract
Diagnostic and therapeutic endoscopy can successfully be performed by applying moderate (conscious) sedation. Moderate sedation, using midazolam and an opioid, is the standard method of sedation, although propofol is increasingly being used in many countries because the satisfaction of endoscopists with propofol sedation is greater compared with their satisfaction with conventional sedation. Moreover, the use of propofol is currently preferred for the endoscopic sedation of patients with advanced liver disease due to its short biologic half-life and, consequently, its low risk of inducing hepatic encephalopathy. In the future, propofol could become the preferred sedation agent, especially for routine colonoscopy. Midazolam is the benzodiazepine of choice because of its shorter duration of action and better pharmacokinetic profile compared with diazepam. Among opioids, pethidine and fentanyl are the most popular. A number of other substances have been tested in several clinical trials with promising results. Among them, newer opioids, such as remifentanil, enable a faster recovery. The controversy regarding the administration of sedation by an endoscopist or an experienced nurse, as well as the optimal staffing of endoscopy units, continues to be a matter of discussion. Safe sedation in special clinical circumstances, such as in the cases of obese, pregnant, and elderly individuals, as well as patients with chronic lung, renal or liver disease, requires modification of the dose of the drugs used for sedation. In the great majority of patients, sedation under the supervision of a properly trained endoscopist remains the standard practice worldwide. In this review, an overview of the current knowledge concerning sedation during digestive endoscopy will be provided based on the data in the current literature.

Abstract
OBJECTIVES To assess the efficacy and safety of propofol sedation for gastrointestinal endoscopy, we conducted a meta-analysis of randomized controlled trials (RCTs) comparing propofol with traditional sedative agents. METHODS RCTs comparing the effects of propofol and traditional sedative agents during gastrointestinal endoscopy were found on MEDLINE, the Cochrane Central Register of Controlled Trials, and EMBASE. Cardiopulmonary complications (i.e., hypoxia, hypotension, arrhythmia, and apnea) and sedation profiles were assessed. RESULTS Twenty-two original RCTs investigating a total of 1,798 patients, of whom 912 received propofol only and 886 received traditional sedative agents only, met the inclusion criteria. Propofol use was associated with shorter recovery (13 studies, 1,165 patients; WMD -19.75; 95% CI -27.65, 11.86) and discharge times (seven studies, 471 patients; WMD -29.48; 95% CI -44.13, -14.83), higher post-anesthesia recovery scores (four studies, 503 patients; WMD 2.03; 95% CI 1.59, 2.46), better sedation (nine studies, 592 patients; OR 4.78; 95% CI 2.56, 8.93), and greater patient cooperation (six studies, 709 patients; WMD 1.27; 95% CI 0.53, 2.02), as well as more local pain on injection (six studies, 547 patients; OR 10.19; 95% CI 3.93, 26.39). Effects of propofol on cardiopulmonary complications, procedure duration, amnesia, pain during endoscopy, and patient satisfaction were not found to be significantly different from those of traditional sedative agents. CONCLUSIONS Propofol is safe and effective for gastrointestinal endoscopy procedures and is associated with shorter recovery and discharge periods, higher post-anesthesia recovery scores, better sedation, and greater patient cooperation than traditional sedation, without an increase in cardiopulmonary complications. Care should be taken when extrapolating our results to specific practice settings and high-risk patient subgroups.

Comparison between the recovery time of alfentanil and fentanyl in balanced propofol sedation for gastrointestinal and colonoscopy: a prospective, randomized study. BMC Gastroenterol 2012; 12:164.

Abstract
Background There is increasing interest in balanced propofol sedation (BPS) titrated to moderate sedation (conscious sedation) for endoscopic procedures. However, few controlled studies on BPS targeted to deep sedation for diagnostic endoscopy were found. Alfentanil, a rapid and short-acting synthetic analog of fentanyl, appears to offer clinically significant advantages over fentanyl during outpatient anesthesia. It is reasonable to hypothesize that low dose of alfentanil used in BPS might also result in more rapid recovery as compared with fentanyl. Methods A prospective, randomized and double-blinded clinical trial of alfentanil, midazolam and propofol versus fentanyl, midazolam and propofol in 272 outpatients undergoing diagnostic esophagogastroduodenal endoscopy (EGD) and colonoscopy for health examination were enrolled. Randomization was achieved by using the computer-generated random sequence. Each combination regimen was titrated to deep sedation. The recovery time, patient satisfaction, safety and the efficacy and cost benefit between groups were compared. Results 260 participants were analyzed, 129 in alfentanil group and 131 in fentanyl group. There is no significant difference in sex, age, body weight, BMI and ASA distribution between two groups. Also, there is no significant difference in recovery time, satisfaction score from patients, propofol consumption, awake time from sedation, and sedation-related cardiopulmonary complications between two groups. Though deep sedation was targeted, all cardiopulmonary complications were minor and transient (10.8%, 28/260). No serious adverse events including the use of flumazenil, assisted ventilation, permanent injury or death, and temporary or permanent interruption of procedure were found in both groups. However, fentanyl is New Taiwan Dollar (NT$) 103 (approximate US$ 4) cheaper than alfentanil, leading to a significant difference in total cost between two groups. Conclusions This randomized, double-blinded clinical trial showed that there is no significant difference in the recovery time, satisfaction score from patients, propofol consumption, awake time from sedation, and sedation-related cardiopulmonary complications between the two most common sedation regimens for EGD and colonoscopy in our hospital. However, fentanyl is NT$103 (US$ 4) cheaper than alfentanil in each case.

Abstract
This study investigated the effects of pre-procedural anxiety (assessed using the Beck Anxiety Inventory) on sedative requirements in 135 patients undergoing sedation for colonoscopy. Deep sedation was defined as loss of consciousness and no response to colonoscopy, and was achieved by target-controlled infusion of propofol. Patients' characteristics, baseline haemodynamic profiles, Beck Anxiety Inventory scores, effect-site propofol concentration at loss of consciousness and characteristics of recovery were recorded. No correlations were found between Beck Anxiety Inventory scores and effect-site propofol concentration at loss of consciousness or baseline haemodynamic profiles. There was no statistical difference in the characteristics of recovery among patients with different levels of anxiety. In conclusion, in patients receiving deep sedation for colonoscopies, the level of pre-procedural anxiety did not relate to the sedative requirement or post-procedural recovery characteristics.

Abstract
BACKGROUND Deep sedation is increasingly used for endoscopy. The impact of sedation level on hemodynamic status, oxygenation, and aspiration risk is incompletely described. AIMS To describe the incidence of intraprocedural cough, hemodynamic changes, oxygen desaturation, and their relationship to clinical factors and sedation level. METHODS Detailed prospective recordings of hemodynamic changes, oxygen desaturation, and cough during 757 nonemergent endoscopic procedures done under sedation using propofol, midazolam, and/or fentanyl. RESULTS Thirteen percent of patients had at least one cough and 3% had prolonged cough. Cough was more common in nonsmokers (P = 0.05), upper endoscopy (P < 0.0001), with propofol (P = 0.0008), longer procedures (P = 0.0001), and hiccups (P = 0.01). The association between supine positioning during colonoscopy and cough approached significance (P = 0.06). Oxygen desaturation was rare (4%) and associated only with deep sedation (P = 0.02). Mean systolic and diastolic blood pressure (BP) dropped by 7.3 and 5.6% respectively. Decreases in systolic BP were more common in whites (P = 0.03), males (P = 0.004), nonsmokers (P = 0.04), during colonoscopy (P < 0.0001), and in patients receiving midazolam and fentanyl (P = 0.01). Heart rate (HR) dropped >20% from baseline in 15% of patients and was more common during colonoscopy (P = 0.002). HR increased >20% in 20% of patients and was more common with coughing (P < 0.0001) and in younger patients (P = 0.0002). No patient required pharmacologic treatment of BP or HR. CONCLUSIONS We have described procedural predictors of cough that may help clinicians reduce the risk of aspiration during endoscopy. Hemodynamic changes during endoscopy are common but largely clinically insignificant.

Abstract
This article reviews the principal aspects related to sedation in endoscopy and to the prevention of adverse events in some of the most frequently performed therapeutic upper gastrointestinal (GI) endoscopic procedures (esophageal dilation and stenting, endoscopic resection of upper GI early neoplasia, hemostasis of upper GI bleeding and percutaneous endoscopic gastrostomy insertion). These procedures have an inherent risk of negative outcomes that cannot be entirely avoided. Endoscopic procedures are best performed by well-trained, competent and thoughtful endoscopists in facilities suited to provide for patient safety. Attention to clinical risk management may effectively reduce the frequency and intensity of adverse events, enhance recognition and early detection, and improve responsiveness.
