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.
Objective To analyze the clinical effect of individualized pain nursing intervention on the pain relieving after ambulatory laparoscopic cholecystectomy (LC) . Methods From March to June 2017, a total of 180 ambulatory LC patients were selected and randomly asigned into the control group and the intervention group with 90 cases in each group. Parecoxib sodium (40 mg) was preoperatively administrated half an hour before the surgery to the patients in both of the two groups. The patients in the control group were treated with routine nursing intervention, while the ones in the intervention group were given individualized pain nursing interventions, including regular pain assessment, preoperative pain health guidance, enhanced education for pain related knowledge, and following the nursing theory of enhanced recovery after surgery. Visual Analogue Scale (VAS) was used to measure the degree of postoperative pain, and the data of dormant pain were collected. Results There was no significant difference between the two groups in VAS one hour after the operation (P>0.05); the VAS scores 2, 6 and 12 hours after the operation gradually decreased in the two groups (P<0.05), and the scores of patients in the intervention group were much lower than those in the control group (P<0.05). The time of pain relieving in the intervention group and the control group was (3.25±1.72) and (5.39±2.06) hours, respectively, and the difference was statistically significant (P<0.05). The incidence of dormant pain in the intervention group (12.2%) was lower than that in the control group (33.3%), and the difference was statistically significant (P<0.05). Conclusion Individualized pain nursing interventions can effectively alleviate the postoperative pain and improve the quality of sleep in ambulatory LC patients.
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.
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.
【Abstract】 Objective To explore the correlation between pain grading, stage of necrosis and bone marrow edema(BME) in nontraumatic osteonecrosis of femoral head (NONFH) so as to strengthen understandings about cl inical significance of BME in NONFH. Methods From October 2004 to October 2006, 97 patients (149 hips) with NONFH were treated. There were 68 males and 29 femals with an average age of 38.8 years (19-62 years). The disease course was from 20 days to 4 years. BME was identified grade 0 to grade 2 according to MRI. Based on grading scale of pain, pain grading were divided into no pain (grade 0), mild pain (grade 1) and moderate or severe pain (grade 2). According to Association Research Circulation Osseous staging system, NONFH were divided into I-IV stages. The incidence rate of BME in each pain grading and stages of necrosis was analyzed respectively. Contingency table analyses and rank sum tests were used to compare the difference of pain grading and stages of necrosis among these groups. Results The total incidence rate of BME was 73.15% (109/149), the incidence rateswere 84.38% in pain groups (108 /128) and 94.12% in the grade 2 (32/34). Pain grading correlated with BME rating (P lt; 0.001).The results of rank sum tests for several independent samples showed significant difference in BME among pain groups(P lt; 0.001). With the advance of pain scale, the mean rank of BME increased gradually(28.19 for grade 0, 78.94 for grade 1 and 96.12 for grade 2). BME was more commonly and clearly seen in stage Ⅱ（77.05%）and stage Ⅲ（82.81%）of NONFH. Stage I-III of NONFH correlated with BME rating (P lt; 0.001). The results of rank sum tests showed significant difference in BME rating among three stages (P lt; 0.001). With the advance of disease, the rank of BME rating increased gradually (39.07 for grade 0, 60.16 for grade 1 and 86.15 for grade 2 ). Conclusion BME is a sign that is accompanied with NONFH. The probabil ity and extent of BME correlated well with the pain and stage of NONFH．The condition of BME can be used as a index for the appraisal of advancement of disease and the judgment of treatment result.
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.
The scientific understanding of pain has stayed on a traditional classic “pain pathway” for many years. However, with the continuous progress of clinical diagnosis, this pathway obviously cannot explain all pain phenomena, and the understanding and interpretation of pain needs to be updated. Based on the influence of comprehensive medicine based on philosophy and the continuous summary and research of clinical cases of somatic symptoms, this paper takes the biological defense mechanism as the basic starting point, analyzes the position of pain in the biological defense mechanism, and reinterprets and defines pain from the new point of view of comprehensive medicine with the new perspective of biological defense mechanism. In addition, this paper also presents the new treatment principles of pain according to the occurrence mechanism through the perspective of biological defense and psychosomatic mechanism, and puts forward new principles of treatment and the view that “defense” is the fundamental purpose of all biology, aiming to provide a reference for the reinterpretation of more diseases and the research on the nature of biological behavior.
ObjectiveWe aimed to further investigate the feasibility of using small bore chest tubes or even without chest tube insertion after da Vinci robot-assisted thoracic surgery. MethodsWe retrospectively analyzed initial 70 patients between September 12, 2014 and March 30, 2015 as a control group at the department of thoracic surgery, the First Affiliated Hospital of Zhejiang University, and proposed four schemes. There are 31 males and 39 females with mean age of 57.1±9.8 (ranged from 30-80 years). We applied those four schemes for the last 30 patients as an experimental group. There are 12 males and 18 females with mean age of 58.8±8.1 (ranged 42-73 years). ResultsThe days in hospital after surgery ranged 2-25 days and there was no severe complication. After the surgery, the pain scores of the trial group are lower than that of the control group. And the schemes 1 and schemes 2 of trial group reduced significantly than the control group (P<0.05). There is no significant difference of the rate of the complication caused by poor drainage between the trial group and the control group (P>0.05). But the pain score after surgery is lower than that of the control group (P<0.05). ConclusionOptimizing thoracic drainage strategy after da Vinci robot-assisted thoracic surgery is safe, possible and helpful to relieve postoperative pain.
Pain is one of the common complications of most diseases. Due to the unknown mechanism of pain, its treatment has been controversial. Repeated peripheral magnetic stimulation for pain has the advantages of non-invasiveness, painlessness, and well-targeted. However, the parameters of repeated peripheral magnetic stimulation for pain are not uniform due to various factors such as frequency, location of action, and coil type. In this paper, the parameters and efficacy of repeated peripheral magnetic stimulation for various kinds of pain such as acute and chronic low back pain, myofascial pain, migraine, peripheral neuralgia and post-traumatic pain are described, in order to providea theoretical basis for future research. In addition, the mechanism of repeated peripheral magnetic stimulation for pain has not been known, and this article will briefly summarize and explain on this.
ObjectiveTo study clinical value of perioperative multimodal analgesia for laparoscopic cholecystectomy based on concept of fast track surgery (FTS). MethodsThe clinical data of 268 patients were analyzed retrospectively, who underwent laparoscopic cholecystectomy in the Department of General Surgery, the 2nd Hospital of Baiyin City from July 2013 to July 2015. All these patients were divided into FTS group and traditional group according to the chronological order, 133 patients in the traditional group were performed traditional perioperative analgesia before August 31, 2014, and 135 patients in the FTS group were performed perioperative multimodal analgesia method based on the concept of FTS after September 1, 2014. The data of both groups were collected and analyzed, including point of numerical rating scale, intestinal function recovery time, intake food time, ambulation time, drainage tube duration, postoperative hospital stay, postoperative sleep time at 72 h, and complications. Results①The points of numerical rating scale at 1 h, 4 h, 8 h, 12 h, 24 h, 48 h, and 72 h in the FTS group were significantly lower than those in the traditional group (P < 0.01).②Compared with the traditional group, the intestinal function recovery time, intake food time, ambulation time, drainage tube duration, and postoperative hospital stay were obviously shorter, the postoperative sleep time at 72 h was obviously longer in the FTS group.③The incidence of nausea and vomiting in the FTS group was significantly lower than that in the traditional group (P < 0.01), the incidences of the other complications such as acid reflux, urinary retention, and breathing difficulty had no significant differences between these two groups (P > 0.05). The satisfaction rate of postoperative analgesic effect in the FTS group was significantly higher than that in the traditional group (P < 0.01). ConclusionsPerioperative multimodal analgesia for laparoscopic cholecystectomy based on concept of FTS is safe and effective. It could achieve painless effect of laparoscopic cholecystectomy.
