Management of Postoperative Pain in Medical Institutions in Shandong Province in China

Postoperative pain management in non-traumatic emergency general surgery: WSES-GAIS-SIAARTI-AAST guidelines

BACKGROUND

Non-traumatic emergency general surgery involves a heterogeneous population that may present with several underlying diseases. Timeous emergency surgical treatment should be supplemented with high-quality perioperative care, ideally performed by multidisciplinary teams trained to identify and handle complex postoperative courses. Uncontrolled or poorly controlled acute postoperative pain may result in significant complications. While pain management after elective surgery has been standardized in perioperative pathways, the traditional perioperative treatment of patients undergoing emergency surgery is often a haphazard practice. The present recommended pain management guidelines are for pain management after non-traumatic emergency surgical intervention. It is meant to provide clinicians a list of indications to prescribe the optimal analgesics even in the absence of a multidisciplinary pain team.

MATERIAL AND METHODS

An international expert panel discussed the different issues in subsequent rounds. Four international recognized scientific societies: World Society of Emergency Surgery (WSES), Global Alliance for Infection in Surgery (GAIS), Italian Society of Anesthesia, Analgesia Intensive Care (SIAARTI), and American Association for the Surgery of Trauma (AAST), endorsed the project and approved the final manuscript.

CONCLUSION

Dealing with acute postoperative pain in the emergency abdominal surgery setting is complex, requires special attention, and should be multidisciplinary. Several tools are available, and their combination is mandatory whenever is possible. Analgesic approach to the various situations and conditions should be patient based and tailored according to procedure, pathology, age, response, and available expertise. A better understanding of the patho-mechanisms of postoperative pain for short- and long-term outcomes is necessary to improve prophylactic and treatment strategies.

A Comprehensive Assessment of The Eight Vital Signs

The term “vital sign” has been assigned to various phenomena with the presumptive intent to emphasize their importance in health care resulting in the emergence of eight vital signs with multiple designations and overlapping terms. This review developed a case definition for vital signs and identified and described the fifth through eighth vital signs. PubMed/Medline, Google and biographical databases were searched using the individual Medical Subject Headings (MeSH) terms, vital sign and fifth, vital sign and sixth, vital sign and seventh, and vital sign eighth. The search was limited to human clinical studies written in English literature from 1957 up until November 30, 2021. Excluded were articles containing the term vital sign if used alone without the qualifier fifth, sixth, seventh, or eighth or about temperature, blood pressure, pulse, and respiratory rate. One hundred ninety-six articles (122 for the fifth vital sign, 71 for the sixth vital sign, two for the seventh vital sign, and one for the eighth vital sign) constituted the final dataset. The vital signs consisted of 35 terms, classified into 17 categories compromising 186 unique papers for each primary authored article with redundant numbered vital signs for glucose, weight, body mass index, and medication compliance. Eleven terms have been named the fifth vital sign, 25 the sixth vital sign, three the seventh, and one as the eighth vital sign. There are four time-honored vital signs based on the case definition, and they represent an objective bedside measurement obtained noninvasively that is essential for life. Based on this case definition, pulse oximetry qualifies as the fifth while end-tidal CO2 and cardiac output as the sixth. Thus, these terms have been misappropriated 31 times. Although important to emphasize in patient care, the remainder are not vital signs and should not be construed in this manner.

Pharmacokinetics and safety of liposomal bupivacaine after local infiltration in healthy Chinese adults: a phase 1 study

Background

Liposomal bupivacaine (LB) is a long-acting formulation of bupivacaine. The safety and efficacy of LB has been demonstrated across surgical procedures. However, pharmacokinetic (PK) parameters and safety of LB in the Chinese population have not been assessed.

Methods

In this single-arm, single center, phase 1, open-label study, PK and safety of local infiltration with LB 266 mg were assessed in healthy Chinese adults. Eligible participants were aged 18 to 55 years with biologic parents and grandparents of Chinese ethnicity, in generally good health (i.e., no clinically significant abnormalities), and with a body mass index (BMI) 19.0 to 24.0 kg/m² (inclusive) and body weight ≥ 50 kg.

Results

Participants (N = 20) were predominantly men (80 %); mean age was 32 years; and mean BMI was 21.8 kg/m². After LB administration, mean plasma levels of bupivacaine rapidly increased during the first hour and continued to increase through 24 h; plasma levels then gradually decreased through 108 h followed by a monoexponential decrease through 312 h. Geometric mean maximum plasma concentration was 170.9 ng/mL; the highest plasma bupivacaine concentration detected in any participant was 374.0 ng/mL. Twenty-two treatment-emergent adverse events were reported (mild, n = 21; moderate, n = 1).

Conclusions

After single-dose administration of LB, PK measures were similar to a previously reported profile in US adults. The highest observed peak plasma concentration of bupivacaine was several-fold below the plasma concentration threshold accepted as being associated with neurotoxicity or cardiotoxicity (2000–4000 ng/mL). These data support that LB is well tolerated and safe in individuals of Chinese descent.

Establishment and Empirical Evaluation of a Quality Indicator System for Postoperative Pain Management

OBJECTIVES

This study aimed to establish a quality indicator system for postoperative pain management and test its reliability, validity, and discrimination in China.

METHODS

We established a quality indicator system using the Delphi method. Further, we designed and administered a survey questionnaire in the orthopedic departments of nine hospitals, located in the Zhejiang and Jiangsu Provinces, through purposive and convenience sampling methods to examine the reliability, validity, and discrimination of the quality indicator system.

RESULTS

We established a quality indicator system to assess structure, process, and outcome measures of postoperative pain management using three first-level, eight subordinate second-level, and 32 subordinate third-level quality indicators. The scale-level content validity indexes of the three sections of the questionnaire, assessing structure, process, and outcomes measures, were 0.99, 0.98, and 0.98, respectively. We identified two common factors from the third section that demonstrated a cumulative variance contribution rate of 80.38% and a Cronbach's α coefficient of 0.95. The total scores and scores of the structure, process, and outcome quality indicators demonstrated statistically significant differences (P < 0.05) between the wards (N = 4) that participated in the "Painless Orthopedics Ward" quality improvement program and those (N = 5) that did not.

CONCLUSIONS

This quality indicator system highlights the need for multidisciplinary cooperation and process characteristics of postoperative pain management, along with interdepartmental quality comparisons. And it demonstrates acceptable reliability, validity, and discrimination; thus it may be completely or partially employed in Chinese hospitals.

The Effectiveness of Using a Nurse-Led Pain Relief Model for Pain Management among Abdominal Surgical Patients: A Single-Center, Controlled before-after Study in China

BACKGROUND

Effective pain management is closely related to the prognosis of patients after surgery. Setting up acute pain service is among the effective strategies to control pain. The operation of acute pain service is mostly dominated by anesthesiologists; however, control of postsurgical pain is still unsatisfactory. Nurses are the main force for providing postoperative care of patients, and their role in acute pain service is crucial. Therefore, in the current study, we have developed a nurse-led pain relief model that emphasizes the central role of nurses during the entire surgical procedure. However, the effect of using this model for pain management among abdominal surgical patients remains unknown.

AIMS

The current study was conducted to investigate the effect of using a nurse-led pain relief model for pain management among abdominal surgical patients.

DESIGN

A single-center, propensity score-matched, controlled before-after study.

METHODS

The patients, hospitalized for abdominal surgery in a university-affiliated hospital from January 2015 to December 2017, were enrolled and divided into group A (hospitalized before nurse-led pain relief model implementation, from January, 2015 to October, 2016) and group B (hospitalized after nurse-led pain relief model implementation, from October, 2016, to December, 2017) using propensity score match assay. The researchers compared the quality of acute pain management, the main side effects of pain management, and nurses' pain knowledge and attitude between group A and group B.

RESULTS

A total of 2851 patients undergoing nonemergency abdominal surgery were enrolled in the current study and were propensity matched 1:1 into two groups with 1,127 subjects in each group. The quality of acute pain management postsurgery was better after implementation of the nurse-led pain relief model. More patients received higher numerical rating scales cores (≥4 points) at indicated time points after surgery in group A compared with group B (14.20% vs. 12.24% 6 hours postsurgery, p = .001; 12.33% vs. 8.52% 12 hours postsurgery, p = .004; 12.95% vs. 3.99% 24 hours postsurgery, p = .036; 16.06% vs. 7.19% 48 hours postsurgery, p = .001). Furthermore, the occurrence of nausea and vomiting during pain management were significantly decreased in patients from group B (nausea: X² = 38.926, p < .05; vomit: X² = 39.302, p < .05). Additionally, after using the nurse-led pain relief model, nurses were more open to improving their knowledge and attitudes to pain management (p < .05).

CONCLUSION

Our study demonstrated that a nurse-led pain relief model can enhance the quality of acute pain management among post-abdominal surgical patients, suggesting that such a model can be an effective intervention for providing a better pain control among postsurgical patients.

Implementation and evaluation of a pain management core competency education program for surgical nurses

Objective

To investigate the effect of a pain management core competency education program on surgical nurses’ pain knowledge and pain management nursing practice behaviors.

Methods

An 8-h education program focused on pain management core competency was provided twice in two weeks including the multidimensional nature of pain, pain assessment, pharmacological and non-pharmacological management, and knowledge application was developed and implemented for surgical nurses by a multidisciplinary team. Multimodal teaching approaches such as didactic teaching and vignettes of cases for nurses to discuss were used. The Clinical Pain Knowledge Test (CPKT) was completed by 135 and 107 nurses from 17 surgical wards pre and post-program, respectively. Two hundred and three patients’ medical records were randomly sampled according to the number of operations in each ward one week before and in the fifth week after the intervention, respectively. Documentation of patients’ postoperative pain management nursing practice behaviors and pain intensity scores were collected.

Results

After the intervention, the CPKT scores of nurses significantly increased from 45.6% ± 12.3% to 54.2% ± 10.2% (t = 5.786, P < 0.001). Nurses’ postoperative pain management nursing practice improved, with proportion of pain assessment documentation increased from 59.6% (121/203) to 74.9% (152/203) (χ² = 10.746, P = 0.001), those using pain intensity assessment tools increased from 81.8% (99/121) to 95.4% (145/152) (χ² = 13.079, P < 0.001), and intramuscular injection of nonopioids decreased from 12.6% (13/103) to 2.7% (3/111) (χ² = 7.598, P = 0.006). Patients’ average worst pain score on the operation day significantly decreased (Z = −2.486, P = 0.013), and scores from the first to the third postoperative day also decreased (Z = −2.172, P = 0.030).

Conclusions

Implementation of a pain management core competency education program for surgical nurses can increase their knowledge of core competencies of pain management, improve selected pain management practices, and decrease patients’ postoperative pain intensity.

Pain Management by Nurses in Level 2 and Level 3 Hospitals in China

BACKGROUND

Pain management practice differs among hospitals in China; however, no studies have examined the association between hospital level and nursing practice of pain management.

AIMS

To evaluate the nursing practice of pain management in orthopedics wards of level 3 and 2 hospitals and compare the differences in pain management regulations, policies, and perceived barriers.

DESIGN

This was a cross-sectional descriptive study.

SETTING

This study was conducted during the 10th International Congress of the Chinese Orthopedic Association, November 19-22, 2015.

PARTICIPANTS

Subjects: The sample included 121 nurses from China.

METHODS

Quantitative research methods were used to assess pain management practice by 121 Chinese nurses as well as barriers to nursing practice.

RESULTS

Nurses in level 3 hospitals were more likely to evaluate patients' pain intensity (85.23% vs. 65.38%, p < .05) and quality (77.27% vs. 53.85%, p < .05) than those in level 2 hospitals. Compared with level 2 hospitals, level 3 hospitals were more likely to participate in the Painless Orthopedics Ward program (53.41% vs. 23.08%, p < .01), conduct pain management knowledge training (88.64% vs. 69.23%, p < .05), and establish pain management regulations (68.18% vs. 34.62%, p < .01). Level 2 hospital nurses reported a higher score for barriers than level 3 hospital nurses (3.27 vs. 2.45, p < .05).

CONCLUSIONS

Nurses from level 2 hospitals received less education on pain management and also paid less attention to and faced more restrictions for pain management than nurses from level 3 hospitals.

Assessing Pain among Chinese Elderly-Chinese Health and Retirement Longitudinal Study

BACKGROUND

Body pain is an important issue among elderly. The objective of this study was to access the association between the socioeconomic status and pain among elderly Chinese.

METHODS

This nationally representative sample cohort study, China Health and Retirement Longitudinal Study (CHARLS), was conducted to estimate pain prevalence and risk factors from Jun 2011 to Mar 2012. Body pain was evaluated by the questionnaires. Logistic regression model was applied to estimate the odds ratio (OR) and 95% Confidence Interval (95% CI) of body pain to identify the potential risk factors.

RESULTS

The prevalence of pain was increased with age (P<0.05). For moderate pain vs. no pain, doing agriculture job (OR 1.17; 95 CI 1.05-1.31), living in urban (OR 0.80; 95 CI 0.72-0.90), having a health problem (OR 1.55; 95 CI 1.20-1.99) is associated with moderate pain. For severe pain vs. no pain, primary school education (OR 0.65; 95 CI 0.54-0.78), junior high school education (OR 0.48; 95 CI 0.39-0.59), having a physical disability (OR 2.71; 95 CI 2.18-3.37), never drinker (OR 0.74; 95 CI 0.60-0.91), environment of urban (OR 0.54; 95 CI 0.46-0.63), having a health problem (OR 2.03; 95 CI 1.45-2.83) are associated with severe pain.

CONCLUSION

Socioeconomic variables such as education, occupation and health conditions are associated with both moderate severe pains.
