Objective To systematically evaluate the effects of magnesium sulfate on postoperative pain and complications after general anesthesia. Methods A literature search was conducted in following databases as The Cochrane Library, EMbase, PubMed, EBSCO, Springer, Ovid, CNKI and CBM from the date of establishment to September 2011 to identify randomized controlled trials (RCTs) about intravenous infusion of magnesium sulfate during general anesthesia. All included RCTs were assessed and the data were extracted according to the standard of Cochrane systematic review. The homogenous studies were pooled using RevMan 5.1 software. Results A total of 11 RCTs involving 905 patients were included. The results of meta-analyses showed that compared with the control group, intravenous infusion of magnesium sulfate during general anesthesia significantly reduced the visual analog scale (VAS) scores at the time-points of 2, 4, 6, 8, 16, and 24 hours, respectively, after surgery, the postoperative 24 hours morphine requirements, and the incidents of postoperative nausea and vomiting (RR=0.61, 95%CI 0.40 to 0.91, P=0.02) and chilling (RR=0.29, 95%CI 0.14 to 0.59, P=0.000 7). Although the incidents of bradycardia (RR=1.93, 95%CI 1.05 to 3.53, P=0.03) increased, there were no adverse events or significant differences in the incidents of hypotension and serum concentration changes of magnesium. Conclusion Intravenous infusion of magnesium sulfate during general anesthesia may obviously decrease the pain intensity, and the incidents of nausea and vomiting and chilling after surgery, without increasing cardiovascular adverse events and risk of hypermagnesemia. The results still need to be confirmed by more high-quality and large-sample RCTs.
Abstract： Objective To evaluate clinical outcomes of painless flexible fiberoptic bronchoscopy in the treatment for pulmonary complications in postoperative pediatric patients with congenital heart diseases. Methods We retrospectively analyzed clinical data of 58 patients who received fiberoptic bronchoscopy for pulmonary complications after surgical repair for atrial septal defect， ventricular septal defect， tetralogy of Fallot， double outlet right ventricle or transposition of the great arteries in First Affiliated Hospital of Harbin Medical University From August 2009 to February 2012. There were 26 male patients and 32 female patients with their age ranging from 20 days to 2 years. Olympus xp-60 fiberoptic bronchoscopy was used for removal of airway secretions and bronchial alveolar lavage under anesthesia with propofol， fentanyl and lidocaine. Pulse oximetry， respiratory sound and chest X-ray changes were observed. Results The examination time of painless fiberoptic bronchoscopy was 10-25 minutes in the 58 patients. After removal of airway secretions by fiberoptic bronchoscopy， their respiratory status improved significantly， pulse oxygen saturation increased by 5%-12%， and their pulmonary crackles were significantly reduced. In 29 patients with atelectasis， their pulmonary lobes demonstrated significant reexpansion in chest X-ray reviews on the next day after fiberoptic bronchoscopy， and 8 patients received another fiberoptic bronchoscopy treatment on the next day to achieve complete pulmonary reexpansion. One patient with severe pulmonary hypertension （PH） stayed in intensive care unit （ICU） for 6 days， 3 patients with transposition of the great arteries stayed in ICU for 5 days， 3 patients with double outlet of right ventricle and moderately high PH stayed in ICU for 4 days， and all the other patients were discharged from ICU within 48 hours after admission. There was no severe complication related to fiberoptic bronchoscopy， except 2 patients with minor nasal mucosa bleeding who were cured with hemostatic drugs and local compression. Conclusion Painless flexible fiberoptic bronchoscopy can significantly enhance clinical outcomes and shorten ICU stay for postoperative pediatric patients with congenital heart diseases.
ObjectiveTo observe the efficacy and safety of etofenamate gel (foscavir+tramadoli hydrochloridum+gabapentin) in the treatment of acute herpes zoster. MethodsForty patients with acute herpes zoster neuralgia treated between January 2013 and June 2014 were randomly divided into two groups:control group and treatment group, with 20 in each. The patients had a visual analogue scale (VAS) pain score of seven or higher. Patients in the control group accepted conventional treatment, while those in the treatment group were treated with conventional treatment combined with etofenamate gel. Two weeks after treatment, VAS score, quality of life and sleep score, and the degree of improvement in skin paresthesia were evaluated and compared between the two groups. ResultsThe VAS score decreased significantly in both the two groups after treatment (P < 0.05), and the decrease in the treatment group was significantly more obvious (P < 0.05). The quality of life, sleep score and the degree of improvement in skin paresthesia were ameliorated significantly after treatment (P < 0.05), and the amelioration in the treatment group was significantly greater (P < 0.05). ConclusionThe early application of Ordofen can strengthen analgesia effect of the conventional treatment, improve the quality of life and sleep, and reduce skin paresthesia.
ObjectiveTo estimate postoperative pain and use of analgesic of patients who underwent video-assisted thoracoscopic surgery(VATS) or robotic assisted thoracoscopic surgery(RATS). MethodsFrom October 2014 through August 2015, 339 patients were treated by surgery in Shanghai Chest Hospital. Among them, 116 patients with intrathoracic lesions who underwent RATS with the da Vinci? Surgical System were as a RATS group with 51 males and 65 females at age of 52.59±11.49 years. Another 223 patients by VATS were as a VATS group with 93 males and 130 females at age of 58.00±10.56 years. We recorded the data of the VAS score and use analgesic of the patients after surgery. ResultsThere was a significant difference in VAS score between the RATS group and the VATS group(3.01±0.18 vs. 5.19±0.14, P<0.05). Astatistical difference of analgesic use between RATS and VATS was also found(1.09±0.12 vs. 1.77±0.10, P<0.05). ConclusionCompared with VATS, the postoperative pain of the patients who underwent RATS is lighter. And the use of analgesic is less.
Objective To evaluate the effects of a preoperative pain education program on patients’ knowledge of postoperative pain management, measures taken for such pain management and the actual postoperative pain. Methods A total of 84 patients undergoing abdominal surgery were non-randomly divided into two groups, 42 in each group. Patients in group A received routine preoperative care and 30 minutes of education about pain management, while patients in group B received routine preoperative care only. All patients completed the Postoperative Pain Management Questionnaire on the second postoperative day. Results Patients in group A achieved higher scores for their knowledge about postoperative pain management than those in group B (Plt;0.05). More patients in group A took non-medical pain relief methods after surgery (Plt;0.05); and patients in group A were able to use the PCA pump more correctly than those in group B (Plt;0.05). No significant differences were observed between the two groups in the frequency of asking for analgesics or their pain score when they requested analgesics (Pgt;0.05). The average score for postoperative pain was lower for group A compared to group B (Plt;0.05). Conclusions A program of preoperative pain education can improve patients’ knowledge of postoperative pain management and encourage them to participate actively in such pain management, so as to further relieve the postoperative pain.
Objective To explore the effect of Frey procedure on patients with chronic pancreatitis, and evaluate pain control as well as the quality of life (QOL) after Frey procedure. Methods The clinical data of 81 patients with chronic pancreatitis who underwent Frey procedure in West China Hospital of Sichuan University from January 2010 to January 2015 were retrospectively analyzed. Izbicki pain score and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30) were used to assess pain and QOL respectively. Results The mean value of operative time were (252±70) minutes (180-430 minutes), the mean value of blood loss were (220±142) mL (100-550 mL), and the mean value of hospital stay were (14.1±4.9) days (8-36 days). After Frey procedure, delayed gastric emptying occurred in 4 patients, hemorrhage occurred in 1 patient, wound infection or fat liquefaction occurred in 6 patients, abdominal infection and pyoperitoneum occurred in 4 patients, and pancreatic fistula occurred in 3 patients. All of the patients were followed up for 4-60 months, and the median time were 28 months. During the follow up period, 11 patients developed diabetes and 10 patients developed steatorrhea, respectively. In addition, the pain related score, including frequency of pain attacks, visual analogue scale of pain, analgetic medication, inability to work, and total pain score, were significantly reduced after Frey procedure (P＜0.001). Moreover, all the functional scales of EORTC -QLQ-C30, except for cognitive function, were improved postoperatively (P ＜0.001). Regarding to the symptom scales, the score of fatigue, pain, loss of appetite, and loss of body weight were significantly lower after surgery (P＜0.050). The scores of QOL after surgery were higher than before surgery (P＜0.001). Conclusion Frey procedure results in good post-operative pain control and significant improvement in qol.
Objective To systematically evaluate the efficacy and safety of injected cyclooxygenase-2 inhibitor for acute postoperative pain. Methods We electronically searched PubMed, EBSCO, Springer, Ovid and CNKI databases from 1999 through Jan. 2009 to identify randomized controlled trials (RCTs) about cyclooxygenase-2 inhibitor or parecoxib sodium for acute postoperative pain. The methodological quality of included RCTs were assessed, and the data was extracted by two reviewers independently according to the Cochrane Handbook. The homogeneous RCTs were pooled using RevMan software, and the non-homogeneous studies evaluted using descriptive qualitative analysis. Results Seven RCTs involving 1939 patients met the inclusion criteria. The results of meta-analyses showed that: ① Efficacy: The comparison of PCA combined parecoxib sodium (successively injected less than 3 days) i.v. with PCA alone: after 24, 48, and 72 hours of the initial dose of parecoxib 40 mg i.v., the percentage of the patients’ global evaluation of study medication (PGESM) described effective (excellent and good) was higher than that of the control group [RR (95%CI) were 1.41 (1.13, 1.75), 1.25 (1.15, 1.35), and 1.30 (1.21, 1.40) respectively]; the percentage of the PGESM described ineffective (fair and poor) was lower than that of the control group [RR (95%CI) were 0.43 (0.26, 0.72), 0.44 (0.34, 0.57), and 0.33 (0.23, 0.48) respectively]. ② Safety: Combination of PCA with parecoxib sodium could lessen the incidence of postoperative fever (RR=0.34, 95%CI 0.22 to 0.53) and nausea and vomiting (RR=0.69, 95%CI 0.57 to 0.83), but not statistically decrease of respiratory depression (RR=0.84, 95%CI 0.38 to 1.83), pruritus (RR=0.91, 95%CI 0.54 to 1.52), and headache (RR=0.77, 95%CI 0.47 to 1.28). Conclusion The combination of PCA with parecoxib sodium successively injected less than 3 days can significantly increase the scores of PGESM, and does not increase the incidence of adverse effects or postoperative complications, and also has the advantage of decreasing postoperative fever, nausea and vomiting.
ObjectiveTo explore the effect of continuous improvement of quality control system on the emergency treatment efficiency for patients with acute ST segment elevation myocardial infarction (STEMI) after the establishment of Chest Pain Center. MethodsWe retrospectively analyzed the differences of theory examination scores acquired by the Chest Pain Center staff one month before and after they got the system training. Moreover, we designated the STEMI patients treated between May and August 2015 after the establishment of Chest Pain Center but before optimization of process to group A (n=70), and patients treated from September to December 2015 after optimization of process to group B (n=55). Then we analyzed the differences between these two groups in terms of the time from patients' arriving to registration, the time from arriving to first order, the length of stay in Emergency Department, and even the time from door to balloon (D2B). ResultsThe scores acquired by Chest Pain Center staff before and after system training were 69.89±6.34 and 87.09±4.39 respectively, with a significant difference (P＜0.05). All the time indicators of both group A and group B were shown as median and quartile. The time from patients' arriving to registration of group A and group B was 6.0 (0.0, 11.0) minutes and 1.0 (0.0, 3.0) minutes (P＜0.05); the time from arriving to first order was 12.8 (9.0, 18.0) minutes and 5.0 (3.0, 9.0) minutes (P＜0.05); the length of stay in Emergency Department was 54.0 (44.0,77.0) minutes and 33.0 (20.0, 61.0) minutes (P＜0.05); and the time of D2B was 107.5 (89.0, 130.0) minutes and 79.0 (63.0, 108.0) minutes (P＜0.05). ConclusionAfter taking measures such as drawing lessons from the past, training staff and optimizing process continuously, we have significantly shortened the acute STEMI patients' length of stay in the Emergency Department, which has saved more time for the following rescue of STEMI patients.
Objective To describe the situation of postoperative pain management in colorectal cancer patient in enhanced recovery after surgery (ERAS) mode, and explore its influenceing factors. Methods From March to December 2017, colorectal cancer patients in ERAS mode in Department of Gastrointestinal Surgery, West China Hospital of Sichuan University were selected. On the third day after surgery, a total of 74 patients with acute pain completed a questionnaire, which was composed of a demographic form, the Houston Pain Outcome Instrument (HPOI), Self-Rating Anxiety Scale, and Social Support Rating Scale. Mean±standard deviation and percentage were used to describe the total score of pain experience, t test, analysis of variance, Spearman correlation analysis were used for single-factor analysis, and multiple linear regression was used for multi-factor analysis. Results The mean total score of pain experience was 15.1±3.8. Single-factor analysis results showed that the affection of pain on daily life (rs=0.270, P=0.020), satisfaction of pain controlling education (rs=–0.283, P=0.015), subjective support (rs=–0.326, P=0.005), and social support utilization (rs=–0.253, P=0.029) were correlated with the total score of pain experience. Multi-factor analysis results showed that satisfaction of pain controlling education (P<0.001) and subjective support (P=0.005) were negative influencing factors of postoperative pain experience score, and severe anxiety (P=0.001) and pain expectation after surgery (P=0.016) were positive influencing factors of postoperative pain experience score. Conclusions Pain management situation is not so bad in these patients. High satisfaction of pain controlling education and high subjective social support are helpful to decrease pain. The medical staff should pay more attention to patients with severe anxiety, and help patients to establish reasonable pain expectation after surgery.
ObjectiveTo explore the feasibility to use pain scale and arterial oxygen partial pressure(PaO2)as screening internal fixation indications for patients with multiple rib fractures. MethodsClinical data of 48 patients with multiple rib fractures who were admitted to Shanghai Pudong Hospital from September 2010 to February 2013 were retrospectively analyzed. Visual analogue scale (VAS) was used for pain assessment. Twenty-four patients whose VAS was greater than or equal to 6 and PaO2 was less than 60 mm Hg 3 days after injury were chosen as the experimental group, including 16 males and 8 females with their age of 49.29±15.73 years. Another 24 patients whose VAS was less than or equal to 5 and PaO2 was greater than 60 mm Hg 3 days after injury were chosen as the control group, including 19 males and 5 females with their age of 48.63±13.49 years. Patients in both groups received rib internal fixation with steel plates. Three days and 1 week after surgery respectively, VAS and PaO2 were compared between the 2 groups. ResultsIn the experimental group, VAS 3 days after surgery was significantly lower than preoperative VAS (4.09±0.93 vs. 8.21±1.18, P < 0.05), and VAS 1 week after surgery was significantly lower than preoperative VAS (3.20±0.98 vs. 8.21±1.18, P < 0.05). In the control group, there was no statistical difference between VAS 3 days after surgery and preoperative VAS (P > 0.05), and there was no statistical difference between VAS 1 week after surgery and preoperative VAS (P > 0.05). Three days after surgery, PaO2 of the experimental group was significantly higher than preoperative PaO2 (61.00±3.47 mm Hg vs. 53.00±3.97 mm Hg, P < 0.05). There was no statistical difference between PaO2 3 days after surgery and preoperative PaO2 in the control group (66.71±5.15 mm Hg vs. 66.00±5.00 mm Hg, P > 0.05). Three days after surgery, pneumonia occurred in 4 patients in the experimental group and 2 patients in the control group (χ2=0.762, P > 0.05). Three days after surgery, pain scale reduction of the experimental group was significantly higher than that of the control group (4.13±1.45 vs. 0.00±0.42, P < 0.05). One week after surgery, pain scale reduction of the experimental group was significantly higher than that of the control group (5.04±1.23 vs. 0.08±0.28, P < 0.05). Three days after surgery, PaO2 increase of the experimental group was significantly higher than that of the control group (7.42±3.59 mm Hg vs. 0.21±0.98 mmHg, P < 0.05). ConclusionIt's reasonable and feasible to use pain scale greater than or equal to 6 and PaO2 less than 60 mm Hg as internal fixation indications for patients with multiple rib fractures.
