Abstract Background Current principles of postoperative pain management are primarily based on the types and extent of surgical intervention. This clinical study measured patient’s self-anticipated pain score before surgery, and correlated the scores with the pain levels and analgesic requirements after surgery. Methods This prospective observational study recruited consecutive patients who received elective surgery in the E-Da Hospital, Taiwan from June to August 2018. Patients were asked to subjectively rate their highest anticipated pain level (numerical rating scale, 0-10) for the scheduled surgical interventions during their preoperative anesthesia assessment. After the operation, the actual pain intensity (NRS 0-10) experienced by the patient in the post-anesthesia care unit and the total dose of opioids administered during the perioperative period were recorded. Results A total of 996 patients were included in the study. Most of the patients (86%) received general anesthesia and 73.9% of them had a history of previous operation. Younger patients (<40 years) (P=0.042) and those took regular benzodiazepine at bedtime (P=0.043) anticipated significantly higher pain levels. Male patients anticipated significantly lower pain intensities than females (odd ratio 1.710; 95% CI 1.254-2.331, P=0.001). Patients who scheduled for laparotomies (P=0.037), orthopedic surgeries (P=0.040) or long procedures (P<0.001) reported higher anticipated pain. Although higher anticipated pain scores were associated with higher postoperative pain levels (P=0.021) and higher total equivalent opioid dose (P=0.001) for acute pain management during the perioperative period, these surgical patients actually experienced less pain than they anticipated at the post-anesthesia care unit. Conclusion This observational study found that patients who are female, younger age (<40 years), use regular benzodiazepines at bedtime and scheduled for long procedures (>2 h), laparotomies or orthopedic surgeries anticipate significantly higher surgery-related pain. Therefore, appropriate preoperative counseling for analgesic control and the management of exaggerated pain expectation in these patients is necessary to improve the quality of anesthesia delivered and patient’s satisfaction.

After the operation, the actual pain intensity (NRS 0-10) experienced by the patient in the post-anesthesia care unit and the total dose of opioids administered during the perioperative period were recorded. Pain scores ³4 on NRS were regarded as being unacceptable levels for anticipated or postoperative pain.Results: A total of 996 patients were included in the study. Most of the patients (86%) received general anesthesia and 73.9% of them had a history of previous operation. Female anticipated significantly higher overall pain intensities than the male patients (adjusted odd ratio 1.532, 95% confidence interval 1.125-2.086; P=0.007). Patients who took regular benzodiazepine at bedtime (P=0.040) and those scheduled to receive more invasive surgical procedures were most likely to anticipate for higher pain intensity at the preoperative period (P<0.001). Although higher anticipated pain scores (NRS³4) were associated with higher postoperative pain levels (P=0.021) and higher total equivalent opioid dose (P=0.001) for acute pain management during the perioperative period, these surgical patients actually experienced less pain than they anticipated at the post-anesthesia care unit.Conclusion: This observational study found that patients who are female, use regular benzodiazepines at bedtime and scheduled for more invasive surgeries anticipate significantly higher surgery-related pain.

Abstract Background Current principles of postoperative pain management are primarily based on the types and extent of surgical intervention. This clinical study measured patient’s self-anticipated pain score before surgery, and compared the anticipated scores with the actual pain levels and analgesic requirements after surgery. Methods This prospective observational study recruited consecutive patients who received elective surgery in the E-Da Hospital, Taiwan from June to August 2018. Patients were asked to subjectively rate their highest anticipated pain level (numeric rating scale, NRS 0–10) for the scheduled surgical interventions during their preoperative anesthesia assessment. After the operation, the actual pain intensity (NRS 0–10) experienced by the patient in the post-anesthesia care unit and the total dose of opioids administered during the perioperative period were recorded. Pain scores ≥4 on NRS were regarded as being unacceptable levels for anticipated or postoperative pain that required more aggressive intervention. Results A total of 996 patients were included in the study. Most of the patients (86%) received general anesthesia and 73.9% of them had a history of previous operation. Female anticipated significantly higher overall pain intensities than the male patients (adjusted odd ratio 1.523, 95% confidence interval 1.126–2.061; P = 0.006). Patients who took regular benzodiazepine at bedtime (P = 0.037) and those scheduled to receive more invasive surgical procedures were most likely to anticipate for higher pain intensity at the preoperative period (P < 0.05). Higher anticipated pain scores (preoperative NRS ≥ 4) were associated with higher actual postoperative pain levels (P = 0.007) in the PACU and higher total equivalent opioid use (P < 0.001) for acute pain management during the perioperative period. Conclusion This observational study found that patients who are female, use regular benzodiazepines at bedtime and scheduled for more invasive surgeries anticipate significantly higher surgery-related pain. Therefore, appropriate preoperative counseling for analgesic control and the management of exaggerated pain expectation in these patients is necessary to improve the quality of anesthesia delivered and patient’s satisfaction.

Abstract Background: Current postoperative pain management principles are primarily based on the type and extent of surgical interventions. This clinical study measured patient’s self-anticipated pain score before surgery and compared the scores with the pain levels and analgesic requirements after surgery.Methods: This prospective observational study recruited consecutive patients who received general anesthesia for elective surgeries in E-Da Hospital (Taiwan) between June and August 2018. Patients were asked to subjectively rate their highest anticipated pain level (numerical rating scale, NRS 0-10) for their scheduled surgical intervention during their preoperative anesthesia assessment. After the operation, the actual pain intensity (NRS 0-10) experienced by the patient in the post-anesthesia care unit (PACU) and the total dose of opioids administered during the perioperative period were recorded. Pain scores ³4 on the NRS were regarded as being unacceptable levels of anticipated or postoperative pain.Results: A total of 857 patients were included in the study. The final database included 49.2% males, and 73.7% of them have had previous operations. The mean anticipated pain score was 4.9±2.5 and 72.2% of the patients reported an anticipated NRS ³4 before their operations. Females anticipated significantly higher overall pain intensities than male patients (adjusted odds ratio 1.695, 95% confidence interval 1.252-2.295; P=0.001). Patients over 40 years of age reported significantly lower overall anticipated NRS scores (4.78±2.49 vs 5.36±2.50; P=0.003). Patients scheduled to receive more invasive surgical procedures were more likely to anticipate high pain intensity in the preoperative period (P<0.001). Higher anticipated pain scores (preoperative NRS³4) were associated with higher actual postoperative pain levels (P=0.032) in the PACU and higher total equivalent opioid use (P=0.001) for acute pain management during the perioperative period.Conclusion: This observational study found that females, younger patients (£40 years), and patients scheduled for more invasive surgeries anticipate significantly higher surgery-related pain. Therefore, appropriate preoperative counseling for analgesic control and management of exaggerated pain expectation in these patients are necessary to improve the quality of anesthesia delivered and patient’s satisfaction.

Abstract Background Current principles of postoperative pain management are primarily based on the types and extent of surgical intervention. This clinical study measured patient’s self-anticipating pain score before operation, and correlated the scores with the actual pain levels and analgesic requirement after operation. Methods This prospective cross-sectional, observational study recruited consecutive patients who received elective surgery in the E-Da Hospital, Taiwan from June to August 2018. Patients were invited to complete a structured questionnaire during preoperative anesthesia assessment that surveyed patient’s self-anticipating pain level (numeric rating scale, NRS 0-10) for the scheduled procedure. The actual pain score (visual analogue scale, VAS) experienced by the patient and the total equivalent dose of opioids administered after operation were recorded. Results A total of 996 patients were recruited and 1 patients were excluded due to incomplete data. Most of the patients (86%) received general anesthesia and 73.9% of them had prior operation history. Patients with younger ages (<40 years) and those took regular benzodiazepine for sleep disorder anticipated significantly higher pain levels. Male patients anticipated significantly lower NRS than females (odd ratio 1.710; 95% CI 1.254-2.331). Patients who scheduled for laparotomy, orthopedic surgery or long procedures had higher anticipating NRS. Although higher anticipating NRS were associated with higher postoperative VAS scores and higher total equivalent opioid dose for acute pain management, these surgical patients actually experienced less VAS than they anticipated at the post-anesthesia care unit. Conclusion This observational study found that female, younger age (<40 years), regular benzodiazepine user and patients who scheduled for long procedure (>2 h), laparotomy or orthopedic surgery are anticipating significantly higher surgical-related pain. Therefore, appropriate preoperative counseling for analgesic control and elimination of unnecessary anticipating pain levels in these patients would be necessary to improve the quality of anesthesia service and patient’s satisfaction.

This case focuses on medication errors and adverse drug events occurring during the perioperative period by asking the question: What are the rates, types, severity, and preventability of medication errors (MEs) and adverse drug events (ADEs) in the perioperative setting during anesthesia care? This prospective observational study reported that approximately 1 in 20 perioperative medication administrations, and every second operation, resulted in an ME and/or an ADE. These rates are markedly higher than those reported by prior retrospective surveys. Process- and technology-based solutions may address the root causes of MEs to reduce their incidence.

Abstract Background: Postcesarean delivery pain leads to several adverse maternal outcomes. The primary objective of this study was to determine the incidence of moderate-to-severe pain after the use of spinal morphine for cesarean delivery. The secondary aim was to identify the factors influencing the moderate-to-severe pain.Methods: This prospective observational study was conducted at a single university hospital. The inclusion criteria were a patient age of ≥ 18 years, and undergoing elective cesarean delivery under spinal anesthesia with intrathecal morphine (200 mcg). Moderate-to-severe pain was defined as a numerical-rating-scale score of more than 3 within 24 hours postoperatively. Patients’ demographic characteristics, preoperative obstetric data, and intraoperative and postoperative data were collected and analyzed.Results: In all, 660 patients were enrolled. As 16 were subsequently removed because they met the study withdrawal criteria, data relating to 644 patients were analyzed. The incidence of moderate-to-severe pain during the first postoperative day was 451/644 patients (70.03%; 95% confidence interval [CI], 66.38%–73.44%). The median pain score (interquartile range [IQR]) was 5 (3–6), with 176/644 (27.33%) of patients requiring a rescue analgesic. A multivariate analysis revealed that two factors were associated with moderate-to-severe pain on the first postoperative day: gestational diabetes (adjusted OR [AOR], 1.849; 95% CI, 1.068–3.203; p-value = 0.028), and intraoperative tubal sterilization (AOR, 1.533; 95% CI, 1.060–2.218; p = 0.023). A significantly higher number of patients experienced moderate-to-severe pain on postoperative Day 1 (451/644 [70.03%]) than Day 2 (348/644 [54.19%]; p < 0.001). The median pain score (IQR) on postoperative Day 2 was 4 (3–5), which was less than that for Day 1 (p < 0.001).Conclusions: A high incidence of moderate-to-severe postoperative pain was found after a single dose of spinal morphine for cesarean delivery. Gestational diabetes and intraoperative tubal sterilization were the independent factors correlated with the pain.Trial registration: Clinicaltrial.gov registration number NCT03205813

Abstract Background Respiratory compromise (RC) including hypoxia and hypoventilation is likely to be missed in the postoperative period. Integrated pulmonary index (IPI) is a comprehensive respiratory parameter evaluating ventilation and oxygenation. It is calculated from four parameters: end-tidal carbon dioxide, respiratory rate, oxygen saturation measured by pulse oximetry (SpO2), and pulse rate. We hypothesized that IPI monitoring can help predict the occurrence of RC in patients at high-risk of hypoventilation in post-anesthesia care units (PACUs). Methods This prospective observational study was conducted in two centers and included older adults (≥ 75-year-old) or obese (body mass index ≥ 28) patients who were at high-risk of hypoventilation. Monitoring was started on admission to the PACU after elective surgery under general anesthesia. We investigated the onset of RC defined as respiratory events with prolonged stay in the PACU or transfer to the intensive care units; airway narrowing, hypoxemia, hypercapnia, wheezing, apnea, and any other events that were judged to require interventions. We evaluated the relationship between several initial parameters in the PACU and the occurrence of RC. Additionally, we analyzed the relationship between IPI fluctuation during PACU stay and the occurrences of RC using individual standard deviations of the IPI every five minutes (IPI-SDs). Results In total, 288 patients were included (199 elderly, 66 obese, and 23 elderly and obese). Among them, 18 patients (6.3 %) developed RC. The initial IPI and SpO2 values in the PACU in the RC group were significantly lower than those in the non-RC group (6.7 ± 2.5 vs. 9.0 ± 1.3, p < 0.001 and 95.9 ± 4.2 % vs. 98.3 ± 1.9 %, p = 0.040, respectively). We used the area under the receiver operating characteristic curves (AUC) to evaluate their ability to predict RC. The AUCs of the IPI and SpO2 were 0.80 (0.69–0.91) and 0.64 (0.48–0.80), respectively. The IPI-SD, evaluating fluctuation, was significantly greater in the RC group than in the non-RC group (1.47 ± 0.74 vs. 0.93 ± 0.74, p = 0.002). Conclusions Our study showed that low value of the initial IPI and the fluctuating IPI after admission to the PACU predict the occurrence of RC. The IPI might be useful for respiratory monitoring in PACUs and ICUs after general anesthesia.

Background: Previous studies on post-operative pain document that most patients continue to experience pain after surgery. This study was done to record the drug use for post- operative pain in laparotomy and to determine the patient characteristics that affect their pain score.Methods: A prospective observational study in 250 adult patients undergoing laparotomy surgery from General Surgery and Obstetrics and Gynaecology (OBG) at a tertiary care hospital.Results: Among patients recruited, 161 (64.4%) were females, 134 (53.6 %) from surgery department, mean age 37.29±14.9 years. Caesarean section 85 (73.27%) followed by meshplasty 46 (34.3%) were most common.Parenteral tramadol 100mg (40%) was the most common analgesic post-operative, subsequently shifted to oral. Epidural analgesia used in 31 (12.4%) patients, only from surgery department. First analgesic received within 6 hrs in 55.5 % in surgery and 44.5 % in OBG (Pearson χ2 =2.535, p = 0.111) with mean time to first analgesic 2.85±2.33 hrs. Pain score, using Numerical Rating Scale (NRS) recorded for 200 (80%) patients showed 76 (30.4%) had severe pain on day 1 which decreased to 12 (4.8%) on day 3. Speciality (p=0.01) and nature of surgery (p=0.05) were significantly associated with severity of pain. Gender [OR = 0.55 (95% CI = 0.26, 1.19), p=0.13], nature of surgery  [2.32 (1.02, 5.32), p=0.05], speciality [0.35 (0.15, 0.80), p=0.01] and surgical category [0.76 (1.01, 5.32), p=0.05] affected pain score on univariate logistic regression, but were not significant on multivariate analysis.Conclusions: Despite the use of opioids and combination analgesics, one third of patients reported severe pain on the first day after surgery.
