ABSTRACT
ABSTRACT BACKGROUND AND OBJECTIVES: Patient-controlled analgesia (PCA) is effective in controlling pain, but has numerous associated risks, such as: hypotension, respiratory depression, seizures and excessive sedation. The promotion of patient safety aims to reduce the risk of unnecessary health injuries and, therefore, it is important to analyze the failures and risk factors present throughout the process proactively. Therefore, the aim of this study was to map the available evidence on the risks of adverse events associated with the PCA technique and patient safety actions. CONTENTS: This is a scoping review conducted according to the JBI methodology, whose research question was based on the PCC strategy. The source of information is open and the search occurred in three stages. The databases used were: Medline/Pubmed; LILACS; CINAHL/ EBSCOhost; CENTRAL; Portal Capes; SCOPUS; Web of Science; Google academic; Brazilian Digital Library of Theses and Dissertations; Portal NICE; and Portal ISMP. The search strategy was divided into 3 stages: the first occurred in Medline and Cinahl to identify articles and index terms on the topic; the second used all keywords in all included databases; the third consisted of tracking searches in the reference lists of the included studies. The search resulted in 1,164 studies, of which 83 were selected based on the inclusion criteria: addressing the risks associated with the PCA pump or safety measures, hospital context, without restriction as to the type of study, language, and year. The studies are distributed in categories: previous diseases, profile of indications, types of opioids, types of pump and infusion, adverse effects, incidents without harm, stages of risk, and safety measures. CONCLUSION: This study made it possible to identify the risks of adverse events associated with the use of PCA in different stages and safety actions, demonstrating that when performed with appropriate patients, trained staff, safe devices, and correct prescription it provides a statistically significant improvement in pain relief, safely with advantages that conventional analgesia does not have.
RESUMO JUSTIFICATIVA E OBJETIVOS: A analgesia controlada pelo paciente (ACP) é eficaz no controle da dor, porém apresenta inúmeros riscos associados, tais como: hipotensão arterial, depressão respiratória, convulsões e sedação excessiva. A promoção da segurança do paciente visa reduzir o risco de lesões desnecessárias à saúde e, para tanto, é importante analisar as falhas e fatores de risco presentes em todo o processo de forma proativa. Portanto, o objetivo deste estudo foi mapear as evidências disponíveis sobre os riscos de eventos adversos associados à técnica de ACP e a ações de segurança do paciente. CONTEÚDO: Trata-se de uma revisão de escopo realizada segundo a metodologia Joanna Briggs Institute para Scoping Reviews, cuja questão de pesquisa se baseou na estratégia PCC (P: população; C: conceito; C: contexto). As bases de dados utilizadas foram: Medline/Pubmed, LILACS, CINAHL/EBSCOhost, CENTRAL, Portal Capes, SCOPUS, Web of Science, Google acadêmico, Biblioteca Digital Brasileira de Teses e Dissertações, Portal NICE, Portal ISMP. A estratégia de busca foi dividida em 3 etapas: a primeira ocorreu na Medline e Cinahl para identificar artigos e termos de índice sobre o tema; a segunda utilizou todas as palavras-chaves em todas as bases de dados incluídas; a terceira consistiu no rastreamento de pesquisas nas listas de referências dos estudos incluídos. A busca resultou em 1.164 estudos, dos quais 83 foram selecionados com base nos seguintes critérios de inclusão: abordagem dos riscos associados à bomba de ACP ou a medidas de segurança, contexto hospitalar, sem restrição quanto ao tipo de estudo, idioma e ano. Os achados sintetizados estão distribuídos em categorias: doenças prévias, perfil das indicações, tipos de opioides, tipos de bomba e de infusão, efeitos adversos, incidentes sem lesões, estágios de risco e medidas de segurança. CONCLUSÃO: Este estudo possibilitou identificar os riscos de eventos adversos associados ao uso da ACP em diferentes estágios e ações de segurança, demonstrando que quando realizada com pacientes adequados, com equipe treinada, dispositivos seguros e prescrição correta, fornece uma melhora estatisticamente significativa no alívio da dor, de forma segura e com vantagens que a analgesia convencional não possui.
ABSTRACT
Abstract Background The effect of regional analgesia on perioperative infectious complications remains unknown. We therefore tested the hypothesis that a composite of serious infections after colorectal surgery is less common in patients with regional analgesia than in those given Intravenous Patient-Controlled Analgesia (IV-PCA) with opiates. Methods Patients undergoing elective colorectal surgery lasting one hour or more under general anesthesia at the Cleveland Clinic Main Campus between 2009 and 2015 were included in this retrospective analysis. Exposures were defined as regional postoperative analgesia with epidurals or Transversus Abdominis Plane blocks (TAP); or IV-PCA with opiates only. The outcome was defined as a composite of in-hospital serious infections, including intraabdominal abscess, pelvic abscess, deep or organ-space Surgical Site Infection (SSI), clostridium difficile, pneumonia, or sepsis. Logistic regression model adjusted for the imbalanced potential confounding factors among the subset of matched surgeries was used to report the odds ratios along with 95% confidence limits. The significance criterion was p < 0.05. Results A total of 7811 patients met inclusion and exclusion criteria of which we successfully matched 681 regional anesthesia patients to 2862 IV-PCA only patients based on propensity scores derived from potential confounding factors. There were 82 (12%) in-hospital postoperative serious infections in the regional analgesia group vs. 285 (10%) in IV-PCA patients. Regional analgesia was not significantly associated with serious infection (odds ratio: 1.14; 95% Confidence Interval 0.87‒1.49; p-value = 0.339) after adjusting for surgical duration and volume of intraoperative crystalloids. Conclusion Regional analgesia should not be selected as postoperative analgesic technique to reduce infections.

Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative patient-controlled intravenous analgesia in pediatric patients undergoing lower extremity orthopedic surgery.Methods:Sixty-eight pediatric patients of both sexes, aged 3-15 yr, of American Society of Anesthesiologists physical status Ⅰor Ⅱ, undergoing elective lower extremity orthopedic surgery under general anesthesia, were divided into 2 groups ( n=34 each) by the random number table method: TEAS group (group T) and control group (group C). In group T, the bilateral Hegu and Neiguan acupoints were stimulated starting from 10 min before induction of anesthesia until the end of procedure, with the frequency of disperse-dense wave of 2/10 Hz, and the current intensity was gradually adjusted to the maximum intensity (10-15 mA) that children could tolerate. In group C, the electrodes were applied to the same acupoints, but electrical stimulation was not applied. The severity of pain was assessed by the Faces Pain Scale-Revised scale immediately after returning to the ward and at 2, 24 and 48 h after operation. The emergence agitation was evaluated using the Pediatric Anesthesia Emergence Delirium scale. The intraoperative consumption of propofol and remifentanil and time to extubation after stopping administration were recorded. The time to first pressing of patient-controlled analgesia (PCA), effective pressing times of PCA on 1st and 2nd days after surgery and postoperative adverse reactions such as postoperative nausea and vomiting, pruritus, drowsiness, and respiratory depression were recorded. Results:Compared with group C, the Faces Pain Scale-Revised scale scores were significantly decreased immediately after returning to the ward and at 2, 24 and 48 h after operation, the incidence of emergence agitation and intraoperative consumption of remifentanil were decreased, the time to extubation was shortened, the time to first pressing of PCA was prolonged, and the effective pressing times of PCA on 1st and 2nd days after surgery were decreased ( P<0.05). There was no significant difference in the intraoperative consumption of propofol and incidence of postoperative adverse reactions between the two groups ( P>0.05). Conclusions:TEAS can effectively enhance the effect of postoperative patient-controlled intravenous analgesia in pediatric patients undergoing lower extremity orthopedic surgery.
ABSTRACT
Objective:To investigate the effect of ropivacaine hydrochloride combined with sufentanil for intraspinal patient-controlled analgesia (PCA) in labor analgesia, and its influence on stress response and pregnancy outcome.Methods:The general data of 97 parturients who underwent intraspinal PCA delivery analgesia in Chengdu Seventh People′s Hospital from April 2019 to March 2021 were retrospectively analyzed. They were divided into the observation group (51 cases) and the control group (46 cases) according to different analgesia methods. The observation group parturients were given ropivacaine hydrochloride combined with sufentanil intraspinal PCA, and the control group parturients were given ropivacaine hydrochloride intraspinal PCA. The numerical scoring system (NRS) was used to evaluate the pain degree of the parturient before, 15 minutes after, 30 minutes after, 45 minutes after analgesia and when the uterine orifice was fully opened. The onset time of analgesia, the time of perfection of analgesia, the amount of ropivacaine hydrochloride, sufentanil and the total amount of analgesic drugs were counted. The levels of serum cortisol (COR), adrenocorticotropic hormone (ACTH) and Norepinephrine (NA) were detected by enzyme-linked immunosorbent assay (ELISA). The time of the first stage of labor, the active stage, the second stage of labor, and the third stage of labor, the amount of vaginal bleeding (during labor and within 2 hours after delivery), the proportion of oxytocin application, normal labor, forceps delivery, lateral perineum resection, and caesarean section, the occurrence of adverse reactions (itching, fever, nausea and vomiting, urinary retention, and fetal bradycardia), and the Apgar score of newborns (1 min and 5 min after birth) were counted.Results:There was no statistically significant difference in the onset time and improvement time of analgesia between the two groups of postpartum women, as well as the NRS scores before and after analgesia at 15, 30, and 45 minutes, as well as when the cervix was fully opened (all P>0.05). The dosage of Ropivacaine hydrochloride and the total amount of analgesics in the observation group were significantly less than those in the control group (all P<0.05). After analgesia, the serum levels of COR, ACTH, and NA in both groups decreased significantly compared to before analgesia (all P<0.05); After analgesia, there was no statistically significant difference in serum COR, ACTH, and NA levels between the two groups (all P>0.05). The second stage of labor in the observation group was shorter than that in the control group, the vaginal bleeding volume and the proportion of caesarean section were lower than those in the control group, the proportion of normal delivery and the Apgar score 1 min after birth of the fetus were higher than those in the control group, and the difference was statistically significant (all P<0.05). There was no statistically significant difference in the analgesic effect and total incidence of adverse reactions between the two groups of postpartum women (all P>0.05). Conclusions:Ropivacaine hydrochloride combined with sufentanil intraspinal PCA can effectively alleviate labor pain, reduce the amount of analgesics, and improve maternal and fetal pregnancy outcomes.
ABSTRACT
Objective:To investigate the effects of different analgesic methods of hydromorphone on analgesic efficacy and sleep quality in patients with refractory cancer pain.Methods:Sixty patients with refractory cancer pain who received three-step analgesic treatment in Quzhou People's Hospital from August 2018 to December 2019 and acquired poor analgesic effects were included in this study. They were randomly assigned to undergo either an intravenous patient-controlled analgesia with hydromorphone (HV group, n = 30) or an intrathecal patient-controlled analgesia with hydromorphone (HI group, n = 30) for 10 consecutive days. The analgesic efficacy in each group was evaluated using the numerical rating scale (NRS) before and 2, 4, 24, 48 hours, and 10 days after administration. The frequency of breakthrough pain (BTP) at each time point was recorded. The sedation effect of medication was evaluated using the Ramsay score. The sleep quality of patients was evaluated using the Pittsburgh sleep quality index (PSQI). The activities of CD 3+, CD 4+, and CD 4+/CD 8+ lymphocyte subsets were measured by flow cytometry at different time points. The adverse reactions within 10 days after treatment were observed and recorded. Results:Before and at each time point after treatment, there were no significant differences in NRS score, the frequency of BTP, Ramsay score, and PSQI score between the two groups (NRS score: t = 0.45, 0.91, 0.52, 1.19, 0.97, 1.92, all P > 0.05; frequency of BTP: t = 0.34, 1.88, 0.86, 1.71, 1.22, 0.76, all P > 0.05; Ramsay score: t = 0.56, 0.46, 0.63, 0.22, 0.99, 0.14, all P > 0.05; PSQI: t = 0.86, 1.25, 1.46, 1.05, 0.57, 1.93, all P > 0.05). At each time point after treatment, the activities of CD 3+, CD 4+, and CD 4+/CD 8+ cells increased in each group, and the activities of CD 3+, CD 4+, and CD 4+/CD 8+ cells in the HI group were significantly higher than those in the HV group (CD 3+: t = 3.72, 3.12, 2.85, 3.13, 2.44, all P < 0.05; CD 4+: t = 3.62, 2.45, 3.31, 3.19, 2.70; all P > 0.05; CD 4+/CD 8+: t = 3.10, 2.74, 2.83, 3.24, 3.41, all P < 0.05). The total incidence of adverse reactions was slightly, but not significantly, lower in the HI group than the HV group [14.00% (7/30) vs. 26.00% (13/30), χ2 = 2.70, P = 0.100]. Conclusion:Compared with intravenous administration of hydromorphone, intrathecal administration of hydromorphone can better effectively relieve pain, decrease the frequency of BTP, improve sleep quality, has a good sedative effect, improve immune function, and has fewer adverse reactions.

ABSTRACT
ABSTRACT BACKGROUND AND OBJECTIVES: Acute postoperative pain affects more than 80.0% of patients and approximately 75.0% of cases are described as moderate to severe. Effective pain relief after cardiac surgery has assumed an important role with the introduction of fast track protocols, requiring better monitoring and patient education for its effectiveness. The present study's objective was to verify if nurses have been playing an active role during pain management, so that this brings positive impacts to the patient in pain control. METHODS: A cross-sectional, descriptive study with a quantitative approach, with data extracted and collected from the digital platform Research Electronic Data Capture in March 2020, referring to data entered in the period between October 2018 and October 2019, totaling 326 patients in the postoperative period of cardiac surgery who used the electronic patient-controlled analgesia pump (PCA) model CADD-Legacy PCA. RESULTS: Predominantly male subjects (73.9%), with a mean age of 59.9±14.9 years. Among the characteristics of the PCA pump, intravenous infusion (98.8%) and bolus/PCA mode (98.5%) stood out. There was adequate monitoring of vital signs in compliance in 96.6% of cases, guidance by the nurse at the time of PCA pump installation in 85.9% and pain control after suspension of the PCA pump in 94.2%. With those who had pain controlled after the end of therapy, there was a predominance of pain control in 95% of patients (p=0.11). CONCLUSION: The results show that well-established protocols, adequate monitoring, and the correct orientation of the patient regarding the use of the device, bring positive impacts after suspension of PCA.

CONCLUSÃO: Os resultados mostraram que protocolos bem estabelecidos, monitoramento adequado e orientação correta do paciente quanto ao uso do dispositivo trazem impactos positivos após suspensão da ACP.
ABSTRACT
Objective:To evaluate the efficacy of compatibility of different opioids for postoperative patient-controlled intravenous analgesia (PCIA) in the patients undergoing gastrointestinal surgery.Methods:A total of 6 556 patients undergoing PCIA after gastrointestinal surgery in the first affiliated Hospital of Air Force military Medical University from May 2018 to March 2022 were retrospectively collected and divided into sufentanil plus nalbuphine group (SN group), hydromorphine plus nalbuphine group (HN group) and sufentanil group (S group). In SN, HN and S groups, the PCIA solutions contained sufentanil 100 μg+ nalbuphine 40 mg, hydromorphone 10 mg+ nalbuphine 40 mg, sufentanil 200 μg, respectively, in 100 ml of normal saline, and the PCA pump was set up with a background infusion at a rate of 1 ml/h, bolus dose 0.5 ml, and lockout interval 10 min.The demographic data, the number of patients with insufficient analgesia at rest and during activity (visual analog scale score≥4) at 24 and 48 h after operation, adverse reactions, time to first flatus and first postoperative off-bed time were collected.Results:Compared with S group, the incidence of insufficient analgesia at rest and during activity, dizziness, nausea and vomiting, effective pressing times of PCA and consumption of drugs in the analgesic pump were significantly decreased at 24 and 48 h after operation in HN group and SN group, the incidence of drowsiness was decreased at 24 h after operation, and the time to first flatus and first postoperative off-bed time were shortened in HN group, and the incidence of somnolence was increased at 48 h after operation in SN group ( P<0.05). Compared with SN group, the incidence of insufficient analgesia at rest at 24 and 48 h after operation was significantly increased, the incidence of insufficient analgesia during activity, dizziness, nausea and vomiting, effective pressing times of PCA and consumption of drugs in the analgesic pump were decreased, the incidence of drowsiness was increased at 24 h after operation, the incidence of somnolence was decreased at 48 h after operation, and the time to first flatus and first postoperative off-bed time were shortened in HN group ( P<0.05). Conclusions:Hydromorphine mixed with nalbuphine provides better efficacy than sufentanil mixed with nalbuphine and sufentanil and is helpful in shortening the recovery time of gastrointestinal function when used for postoperative PCIA in the patients undergoing gastrointestinal surgery.
ABSTRACT
Objective:To evalaute the efficacy of butorphanol mixed with different doses of hydromorphone in improving patient-controlled intravenous analgesia (PCIA) after secondary cesarean section.Methods:Two hundred American Society of Anesthesiologists physical status Ⅱsingleton pregnant parturients, aged 18-45 yr, at 37-42 week gestation, with body mass index≤30 kg/m 2, undergoing elective secondary cesarean section under combined spinal-epidural anesthesia, were allocated to one of 4 groups ( n=50 each) using a random number table method: butorphanol (group B) and butorphanol mixed with different doses of hydromorphone groups (group BH 1, group BH 2 and group BH 3). Flurbiprofen 50 mg, butorphanol 1 mg and granisetron 3 mg were intravenously injected after delivery during operation.The analgesic pump was connected and turned on at the end of operation.The PCIA solution contained butorphanol 0.24 mg/kg and granisetron 6 mg in group B, butorphanol 0.24 mg/kg and hydromorphone 0.06 mg/kg and granisetron 6 mg in group BH 1, butorphanol 0.24 mg/kg and hydromorphone 0.09 mg/kg and granisetron 6 mg in group BH 2, butorphanol 0.24 mg/kg and hydromorphone 0.12 mg/kg and granisetron 6 mg in group BH 3.The PCIA solution was diluted with normal saline to 150 ml, and the patient-controlled analgesia (PCA) pump was set up to deliver a 3.0 ml bolus dose with a 15-min lockout interval and background infusion at 2.5 ml/h in all the four groups.The degree of pain was evaluated using the VAS score.When the VAS score>5 points after pressuring analgesia pump at rest, flurbiprofen axetil 50 mg was intravenously injected for rescue analgesia.VAS scores during movement, at rest and during uterine contraction and observer′s assessment of alertness/sedation scale score were recorded at 3, 6, 24 and 48 h after operation.The requirement for rescue analgesia, effective pressing times of PCA, overall satisfaction score, OAA/S score<5, adverse reactions and time to the first flatus were recorded within 48 h after operation. Results:Compared with group B, VAS scores in different states were significantly decreased after operation, the effective pressing times of PCA were decreased within 48 h after surgery, and the overall satisfaction score was increased in BH 1, BH 2 and BH 3 groups ( P<0.05). Compared with group BH 1, no significant change was found in VAS score in different states after operation in group BH 2 ( P>0.05), and VAS score was significantly decreased at rest after operation in group BH 3 ( P<0.05). There was no significant difference in VAS scores between group BH 2 and group BH 3 ( P>0.05). There were no significant differences in the requirement for rescue analgesia, effective pressing times of PCA and overall satisfaction of the puerperae among BH 1, BH 2 and BH 3 groups ( P>0.05). There was no significant difference in the time to the first flatus after operation, requirement for rescue analgesia and incidence of observe′s assessment of alterness/sedation scale score<5 and adverse reactions among the four groups ( P>0.05). Conclusions:Compared with butorphanol alone, butorphanol mixed with hydromorphone is helpful in reducing maternal pain and improving the overall satisfaction, with fewer adverse reactions.Butorphanol 0.24 mg/kg mixed with hydromorphone 0.09 mg/kg is recommended.
ABSTRACT
Objective:To evaluate the efficacy of S-ketamine mixed with hydromorphone for improving patient-controlled intravenous analgesia (PCIA) after lumbar spinal surgery.Methods:Ninety-six American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients, aged 18-64 yr, with body mass index of 18.5-29.9 kg/m 2, scheduled for elective lumbar fusion surgery under general anesthesia, were divided into 2 groups ( n=48 each) using a random number table method: hydromorphone for PCIA group (group H) and S-ketamine mixed with hydromorphone for PCIA group (group S+ H). PCIA was performed at the end of operation.PCIA solution contained hydromorphone 0.05 mg/ml mixed with S-ketamine 0.25 mg/ml in group S+ H and hydromorphone 0.05 mg/ml in group H. The PCIA pump was set up to deliver a 2 ml bolus dose with a 10-min lockout interval, background infusion at 2 ml/h and total volume of 200 ml.When the numerical rating scale score ≥4 and analgesia was ineffective by pressing the PCA pump for 3 consecutive times, hydromorphone 0.2 mg was intravenously injected as rescue analgesic.The cumulative consumption of hydromorphone (consumption for analgesic pump and consumption for rescue analgesia) and occurrence of adverse reactions such as pruritus, respiratory depression, nausea, vomiting, drowsiness, dizziness, headache, hallucinations and nightmares within 48 h after operation were recorded.The patients′ satisfaction with analgesia was recorded at 48 h after operation.The time to first flatus after operation and quality of recovery (QoR-15 scale) at 24 and 48 h after operation were recorded. Results:Compared with group H, the cumulative consumption of hydromorphone within 48 h after surgery were significantly reduced, the patients′ satisfaction with analgesia was increased, the time to first flatus after operation was shortened, QoR-15 scores were increased at 24 and 48 h after operation ( P<0.05), and no significant change was found in the requirement for rescue analgesia and incidence of adverse reactions within 48 h after surgery in group S+ H ( P>0.05). Conclusions:Compared with PCIA with hydromorphone, S-ketamine mixed with hydromorphone can reduce postoperative consumption of hydromorphone, increase satisfaction with analgesia, and promote early postoperative recovery after lumbar spinal surgery.
ABSTRACT
Objective:To investigate the analgesic effects of butorphinol used in intravenous patient-controlled analgesia after laparoscopic gynecological surgery.Methods:Ninety-eight patients who underwent laparoscopic gynecological surgery in Linhai First People's Hospital between March 2018 and November 2019 were included in this study. They were randomly divided into control and observation groups, with 49 patients per group. After surgery, intravenous patient-controlled analgesia with either ondansetron (control group) or ondansetron combined with butorphanol (observation group). At 2, 12 and 24 hours after surgery, visual analogue scale score and Ramsay sedation scale score were compared between the two groups. Heart rate, systolic blood pressure, and respiratory rate at 0 and 30 minutes after surgery were compared between the two groups. The incidences of postoperative adverse reactions were compared between the two groups.Results:At 2, 12 and 24 hours after surgery, visual analogue scale scores in the observation group were (1.27 ± 0.50) points, (2.24 ± 0.63) points, and (1.71 ± 0.55) points respectively, which were significantly lower than (1.52 ± 0.47) points, (3.20 ± 0.58) points, (2.23 ± 0.59) points in the control group ( t = 2.55, 7.84, 4.51, all P < 0.05). At 2, 12 and 24 hours after surgery, Ramsay sedation scale scores in the observation group were (4.22 ± 0.41) points, (3.22 ± 0.43) points, and (3.02 ± 0.31) points, respectively, which were significantly higher than (4.02 ± 0.32) points, (3.01 ± 0.27) points, (2.73 ± 0.35) points in the control group ( t = -2.69, -2.89, -4.34, all P < 0.05). There were no significant differences in heart rate, systolic blood pressure, and respiratory rate measured at 0 and 30 minutes after surgery between the two groups (all P > 0.05). There were no significant differences in use of pethidine and the incidence of adverse reactions between the two groups (both P > 0.05). Conclusion:Butorphinol helps improve the analgesic and sedative effects after laparoscopic gynecological surgery and has little impact on patient's breathing and circulation.
ABSTRACT
Objective:To investigate the analgesic effects of ultrasound-guided rectus abdominis sheath block (RSB) in open gastrectomy.Methods:Forty-one patients with gastric cancer who underwent open gastrectomy in Binzhou Hospital of Traditional Chinese Medicine from December 2019 to December 2020 were included in this study. They were randomly assigned to undergo either RSB with 40 mL of 0.375% ropivacaine (group A, n = 21) or RSB with 40 mL of 0.9% sodium chloride injection (group B, n = 20) based on total intravenous anesthesia. After skin sutures, patient-controlled analgesia (PCA) was performed. Intraoperative dose of remifentanil and postoperative dose of PCA drug were compared between the two groups. Results:Intraoperative dose of remifentanil was significantly lower in the group A than that in the group B [(1 021.4 ± 172.0) μg vs. (1 415.0 ± 330.6) μg, t = -4.04, P = 0.001]. Postoperative doses of PCA drug used by 1 and 2 hours after surgery were (1.14 ± 0.90) mL and (0.85 ± 0.70) mL respectively in group A, which were significantly lower than (1.85 ± 0.70) mL and (1.45 ± 1.00) mL in the group B ( t = -5.96, -2.75, P < 0.001, P = 0.009). There were no significant differences in postoperative doses of PCA drug used by 3, 6, 12, 24, 48 and 72 hours after surgery between the two groups (both P > 0.05). Conclusion:RSB with 40 mL of ropivacaine applied to both sides of the incision before open gastrectomy can reduce the dose of remifentanil used during surgery and the dose of PCA drug used within 2 hours after surgery.
ABSTRACT
Objective:To evaluate the efficacy of esketamine for patient-controlled intravenous analgesia (PCIA) in elderly patients undergoing modified radical mastectomy for breast cancer.Methods:Ninety elderly female patients, aged 65-78 yr, weighing 46-75 kg, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, undergoing elective modified radical surgery for breast cancer under general anesthesia, were divided into 2 groups ( n=45 each) using a random number table method: esketamine PCIA group (group E) and sufentanil PCIA group (group S). Anesthesia was induced with target-controlled infusion of propofol, intravenous atracurium besylate and sufentanil and maintained with target-controlled infusion of propofol and remifentanil and intermittent intravenous boluses of cis-benzenesulfonic acid atracurium.The patients were connected to an analgesic pump for PCIA at 10 min before completion of operation.The PCIA solution in group E contained esketamine 2 mg/kg, ketorolac tromethamine 90 mg and tropisetron 5 mg in 100 ml of normal saline.The PCIA solution in group S contained sufentanil 1 μg/kg, ketorolac tromethamine 90 mg and tropisetron 5 mg in 100 ml of normal saline.The PCA pump was set up with a 1.5 ml bolus dose, a 15 min lockout interval and background infusion at a rate of 1.5 ml/h, and the analgesia was performed until 48 h after operation.When numeric rating scale score ≥ 4 points and the efficacy of patient-controlled analgesia was not good, tramadol 100 mg was intravenously injected for rescue analgesia.Steward recovery scores were recorded at 4, 8, 24 and 48 h after operation.The requirement for rescue analgesia, effective pressing times of analgesic pump and time to first flatus were recorded within 48 h after operation.The nausea and vomiting, respiratory depression, dizziness and pruritus within 48 h after operation and delirium within 7 days after operation were recorded.The 40-item Quality of-Recovery scale was used to evaluate the early postoperative recovery of patients at 24 and 48 h after operation. Results:Compared with group S, the 40-item Quality of Recovery scale score was significantly increased at each time point, postoperative time to first flatus was shortened, the incidence of postoperative nausea and vomiting and pruritus was decreased ( P<0.05), and no significant change was found in the Steward recovery score at each time point after operation, effective pressing times of PCA and requirement for rescue analgesia in group E ( P>0.05). Conclusions:Esketamine provides better efficacy than sufentanil when used for PCIA in elderly patients undergoing modified radical mastectomy for breast cancer.
ABSTRACT
Objective:To preliminarily evaluate the effectiveness and safety of nalbuphine for patient-controlled intravenous analgesia (PCIA) after cesarean section.Methods:This study was a single arm clinical trial.Sixty parturients, aged 20-44 yr, weighing 50-80 kg, of American Society of Anesthesiologists physical status ⅠorⅡ, scheduled for cesarean section with epidural anesthesia, were enrolled in this study.PCIA was performed when visual analogue scale (VAS) score for postoperative pain ≥3 points following cesarean section.A bolus of nalbuphine 10 mg was intravenously injected as a loading dose.PCIA pump solution contained 110 mg nalbuphine diluted to 200 ml with normal saline.The pump was set up with a background infusion at a rate of 4 ml/h, 2 ml bolus dose and 15 min lockout interval.The VAS scores for pain at rest and during activity and uterine contraction pain, Ramsay sedation scores and adverse reactions were observed within 48 h after surgery.Results:The VAS scores for pain at rest and during activity and uterine contraction pain were all ≤3 points, the Ramsay scores were maintained at 2-4 points, hemodynamic parameters were maintained in the normal range, and no adverse reactions such as nausea and vomiting, drowsiness, hyperhidrosis, dizziness, pruritus, and respiratory depression occurred.Conclusion:PCIA with nalbuphine given according to the method mentioned above has good feasibility when used for analgesia following cesarean section.
ABSTRACT
Objective:To evaluate the effect of epidural labor analgesia administration methods on occurrence of postpartum urinary retention in nulliparous parturients through a comparison between programmed intermittent epidural bolus (PIEB) and continuous epidural infusion.Methods:Two hundred nulliparous parturients who were at full term with a singleton fetus in vertex presentation, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, aged 22-35 yr, with body mass index of 22.4-42.6 kg/m 2, were divided into 2 groups ( n=100 each) using a random number table method: continuous epidural infusion group (group CEI) and group PIEB.Patient-controlled epidural analgesia (PCEA) was performed in active phase of labor (cervical dilatation≥1 cm) during the first stage of labor.The PCEA solution contained the mixture (10 ml) of 0.1% ropivacaine with 0.5 μg/ml sufentanil.The PCEA pump was set up to deliver a 5-ml bolus dose with a 30-min lockout interval.The analgesia solution contained the mixture (100 ml) of 0.08% ropivacaine and sufentanil 0.5 μg/ml.In group CEI, the drugs were given at 8 ml/h immediately after the initial dose.PIEB regimens were programmed as 8 ml over 80 s once an h after the initial bolus, and the administration was stopped after delivery of fetus.The labor time, consumption of analgesia solution and the incidence of postpartum urinary retention were recorded. Results:Compared with group CEI, the duration of the second stage of labor was significantly shortened, and consumption of analgesia solution and the incidence of postpartum urinary retention were decreased in group PIEB ( P<0.05). Conclusion:Compared with the continuous epidural infusion, the application of PIEB in labor analgesia can reduce the incidence of postpartum urinary retention in nulliparous parturients.
ABSTRACT
Objective:To evaluate the effects of patient-controlled intravenous analgesia (PCIA) with esketamine on postpartum depression (PPD) in puerpera undergoing cesarean section.Methods:A total of 300 American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients, aged 25-35 yr, with body mass index≤35 kg/m 2, scheduled for elective cesarean section under spinal anesthesia, were divided into 2 groups ( n=150 each) by a random number table method: control group (group C) and esketamine group (group E). PCIA was performed at the end of surgery.In group C, the PCIA solution contained sufentanil citrate 50 μg, butorphanol tartrate 12 mg and metoclopramide injection 20 mg in 200 ml of 0.9% normal saline.In group E, the PCIA solution contained esketamine 1 mg/kg, sufentanil citrate 50 μg, butorphanol tartrate 12 mg and metoclopramide injection 20 mg in 200 ml of 0.9% normal saline.The PCA pump was set to deliver a background infusion of 4 ml/h and a bolus dose of 4 ml at 30 min lockout interval.The analgesia lasted for 48 h after surgery, and the visual analog scale (VAS) score was maintained<4 points.Acetaminophen 0.5 g was administered orally as a rescue analgesic when VAS score≥4 points and pain was still unrelieved after PCA pump was pressed twice in a row.The Edinburgh Postnatal Depression Scale (EPDS) was performed at 1 day before and at 3, 7 and 42 days after surgery.Depression was classified on EPDS as mild (score≥10) and severe (score≥13). The patients with preoperative depression were excluded from the study.The occurrence and degree of depression were recorded.The requirement for rescue analgesia within 0-6 h, 6-12 h, 12-24 h and 24-48 h after surgery and development of adverse effects within 3 days after surgery were recorded. Results:Compared with group C, the incidence of PPD was significantly decreased and degree was reduced at 3 and 7 days after surgery, incidence of rescue analgesia was decreased in different time periods ( P<0.05), and no significant change was found in the incidence of adverse effects in group E ( P>0.05). Conclusion:Esketamine can not only provide good postoperative analgesia but also improve PPD in puerpera when it is used for PCIA after cesarean section.
ABSTRACT
Objective:To investigate the effects of different doses of dexmedetomidine combined with tramadol on intravenous analgesia and sleep quality after cesarean section.Methods:One hundred and twenty pregnant women who underwent cesarean section in Zhongshan Boai Hospital from March 2019 to July 2020 were selected. They were randomly divided into four groups, with 30 patients in each group. The patients in group Awere given patient controlled anesthesia with tramadol 800 mg+ tropisetron 5mg after cesarean section, and the patients in group B1, B2 and B3 were given 1.0, 1.5, 2.0 μg/kg dexmedetomidine on the basis of group A. The scores of exercise and rest of visual analogue scale (VAS) at 6, 12, 24 and 48 h after the surgery were observed. The scores of Athens insomnia scale (AIS) before and after surgery were compared. The Ramsay sedation scores and basic vital signs were recorded, compared and analyzed at 6, 12, 24 and 48 h after the surgery. The incidence of adverse reactions within 48 h after the surgery was counted in the four groups.Results:The scores of exercise and rest of VAS at 6, 12, 24 and 48 h after the surgery in four groups had significant differences ( P<0.05). The scores of group A were the highest, and next were the group B1, B2 and B3. The scores of AIS at 1 and 2 d after surgery in four groups had significant differences ( P<0.05).The scores of group A were the highest, and next were the group B1, B2 and B3.The level of oxyhemoglobin saturation (SpO 2) after surgery in four groups had no significant difference ( P>0.05). The levels of systolicblood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) after surgery in four groups had significant differences ( P<0.05). The levels of SBP, DBP, HR in group A were the highest, and next were the group B1, B2 and B3. Thelevels of SBP, DBP, HR in group A, B1 and B2 were in normal range, but the levels of SBP, DBP and HR in group B3 were in lower limits of normal, the level of HR in some patients was below normal. The Ramsay sedation scores at 6, 12, 24 and 48 h after surgery in the four groups had significant differences ( P<0.05). Ramsay sedation scores in group A were the lowest, and next were the group B1, B2 and B3. The total incidence of adverse reactions in group B3 was the highest with 33.33%(10/30), and in group B1 was the lowest with 6.67%(2/30). Conclusions:Medium dose of dexmedetomidine (1.5 μg/kg) combined with tramadol has a good effect on postoperative intravenous sedation and analgesia in patients after cesarean section, which can improve the sleep quality of patients. Besides, the drug safety can be guaranteed.

OBJECTIVE：To investigate the effects of parecoxib sodium ，flurbiprofen axetil and lornoxicam combined with patient controlled intravenous analgesia （PICA） on postoperative analgesia in patients undergoing gynecological laparoscopic surgery and its effect on serum related factors. METHODS ：A total of 280 patients who underwent gynecologic laparoscopic surgery in the Second Affiliated Hospital of Hainan Medical University from Mar. 2017 to Mar. 2019 were randomly divided into control group （group C ），parecoxib sodium group （group P ），and flurbiprofen axetil group （group F ）and lornoxicam group （group L ）acording to random number table ，with 70 patients in each group. Four groups of patients received Sodium chloride injection 5 mL，Parecoxib sodium for injection 40 mg，Flurbiprofen axetil injection 50 mg and Lornoxicam for injection 8 mg （added 8 mg when the effect was not good ）intravenously at 30 min before the end of surgery. At the end of surgery ，they were given PICA of Sufentanil citrate injection and Dizosin injection for analgesia. The situation of pain and nausea symptom were evaluated at 6，12，24 and 48 h after surgery by using numerical rating scale （NRS）. The levels of serum CRP ，IL-6，SP and PGE 2 were detected by chemiluminescence method and ELISA. The times of pressing PICA pump and the dosage of analgesic were recorded in 4 groups within 24 h after surgery. The ADRs of patients within 48 h after surgery were recorded ，such as bloating ， dizziness，itchy skin ，respiratory depression and urinary retention. RESULTS ：At different time points ，the NRS scores of pain of group P ，F and L were significantly lower than those of group C ；and 48 h after surgery ，NRS score of pain of group L was significantly lower than those of group P and F （P＜0.05）. There was no statistical significance in the level of CRP ，IL-6，SP and PGE2 of 4 groups before surger （P＞0.05）. The CRP ，IL-6，SP and PGE 2 levels at each time point after surgery of group P ，F and L were significantly lower than those of group C ；compared with group P ，serum level of SP at 48 h after surgery as well as serum levels of PGE 2 at 12，24 and 48 h after surgery were significantly decreased in group F ，and serum level of IL- 6 at 48 h after surgery，serum levels of SP at 24 and 48 h after surgery ，serum levels of PGE 2 at 12，24，48 h after surgery were decreased significantly in group L ；compared with group F ，serum level of SP at 48 h after surgery as well as serum levels of PGE 2 at 12， 24，48 h after surgery were all decreased significantly in group L （P＜0.05）. There was no statistical significance in the incidence of anausea and vomiting among 4 groups（P＞0.05）. CONCLUSIONS ：Parecoxib sodium ，flurbiprofen axetil and lornoxicam combined with PICA can effectively relieve the pain of patients after gynecological laparoscopic surgery and reduce the levels of serum related factor ，and lornoxicam has the most obvious effect.
ABSTRACT
To evaluate the value of oxycodone hydrochloride for postoperative pain management in patients undergoing patient-controlled intravenous analgesia(PCIA). The medical records on postoperative pain management in our department from January 1 to June 30,2018,were retrospectively analyzed.Totally 136 patients were assigned into oxycodone,sufentanil,or morphine groups according to the opioid used in the PCIA.Patients were assessed for postoperative pain severity(scored with NRS)and adverse reactions 24,36,and 48 hours after surgery.The area under curve(AUC)was calculated. The score of pain at exercise was significantly lower in the oxycodone group(2.2±2.4)than in the sufentanil group(3.4±2.1)(=0.305,=0.0126)or the morphine group(3.4±1.7)(=0.104,=0.0277)36 hours after surgery.AUC at rest was significantly lower in the oxycodone and morphine groups than in the sufentanil group(29.00,27.00,and 40.01,respectively);in contrast,AUC at exercise was significantly lower in the oxycodone group(63.17)than in the sufentanil and morphine groups(82.00 and 80.93,respectively).The consumption of opioids was significantly higher in the sufentanil group[(37.2±16.1),(46.1±24.3),(64.4±33.4)mg]than in the oxycodone group[(20.4±14.8)(=3.571,=0.001),(24.2±16.1)(=4.63,<0.0001),(34.4±25.1)mg(=6.409,<0.0001)]or the morphine group[(16.6±11.7)(=4.233,<0.0001),(20.5±14.1)(=5.250,<0.0001),(28.8±19.0)mg(=7.354,<0.0001)]24,36,48 hours after surgery.The oxycodone group experienced less vomiting(=11.360,=0.003)and early termination of PCIA(=7.914,=0.019)compared with the other two groups. Oxycodone can be used for postoperative PCIA.It can alleviate a variety of postoperative pain,with superior analgesic efficiency and safety to sufentanil and morphine.
