BackgroundThe pharmaceutical industry invests heavily in promotion, and it uses a variety of promotional strategies to influence physicians’ prescribing decisions. Within this context, medical representatives (MRs) are the key personnel employed in promoting their products. One significant consequence of the interactions between physicians and medical representatives is a conflict of interests which may contribute to the over prescribing of medications and thus negative effects on patients’ health and economics. There is limited detailed information published on the reasons why physicians interact with pharmaceutical representatives. This study aims to qualitatively explore physicians’ attitudes about interactions with medical representatives and their reasons for accepting the medical representatives’ visits.MethodsIn-depth interviews were used to gain a better understanding of physicians’ perceptions of medical representative visits. A total of 32 physicians from both private and public hospitals were interviewed. The recordings of the interviews were transcribed verbatim and subject to thematic analysis using a framework analysis approach.ResultsThe present qualitative study found that the majority of the physicians had positive interactions with medical representatives. The physicians’ main reasons stated for allowing medical representatives’ visits are the social contacts and mutual benefits they will gain from these representatives. They also emphasized that the meeting with representatives provides educational and scientific benefits. A few physicians stated that the main reasons behind refusing the meeting with medical representatives were lack of conviction about the product and obligation to prescribe medicine from the representative company. Most of the physicians believed that they were under marketing pressure to prescribe certain medicines.ConclusionsAlthough physicians are aware that the medical representatives could influence their prescribing decision, they welcome representatives to visit them and consider receiving free samples, gifts and various kinds of support as a normal practice. The findings provided insight into possible target areas for educational interventions concerning pharmaceutical marketing. Such a finding will provide the basis for policymakers in the public and private health sector in Yemen to develop a suitable policy and regulations in terms of drug promotion.
Background:Caudal analgesia is the most commonly used technique providing intra- and postoperative analgesia for various pediatric infraumbilical surgical procedures but with the disadvantage of short duration of action after single injection. Caudal dexamethasone and magnesium could offer significant analgesic benefits. We compared the analgesic effects and side-effects of dexamethasone or magnesium added to caudal ropivacaine in pediatric patients undergoing inguinal hernia repair.Materials and Methods:A total of 105 (1-6 years) were randomly assigned into three groups in a double-blinded manner. After a standardized sevoflurane in oxygen anesthesia, each patient received a single caudal dose of ropivacaine 0.15% 1.5 mL/kg combined with either magnesium 50 mg in normal saline 1 mL (group RM), dexamethasone 0.1 mg/kg in normal saline 1 mL (group RD), or corresponding volume of normal saline (group R) according to group assignment. Postoperative analgesia, use of analgesics, and side-effects were assessed during the first 24 h.Results:Addition of magnesium or dexamethasone to caudal ropivacaine significantly prolonged analgesia duration 8 (5-11) h and 12 (8-16) h, respectively compared with 4 (3-5) h with the use of ropivacaine alone. The incidence of postoperative rescue analgesia was significantly higher in group R compared with groups RM and RD. The time to 1st analgesic dose was significantly longer in groups RM and RD (500 ± 190 and 730 ± 260 min) respectively compared with group R (260 ± 65 min). Group R patients achieved significantly higher Children's Hospital of Eastern Ontario Pain Scale and Faces Legs Activity Cry Consolability scores (4th hourly) compared with groups RM and RD patients (8th and 12th hourly, respectively).Conclusion:The addition of dexamethasone or magnesium to caudal ropivacaine significantly prolonged the duration of postoperative analgesia in children undergoing inguinal hernia repair. Also the time to 1st analgesic dose was longer and the need for rescue postoperative analgesic was reduced and without increase in incidence of side effects.
Background: The ultrasound (US)-guided erector spinae plane (ESP) block and oblique subcostal transversus abdominis plane (OSTAP) block are used to decrease postoperative pain and subsequently opioids consumption. Aim: The aim was to test the hypothesis that US-guided ESP blocks can produce more reduction in opioid usage during the first 24 h after laparoscopic cholecystectomy when compared to OSTAP block. Settings and Design: Seventy adult patients (20–60 years old) who were planned to undergo elective laparoscopic cholecystectomy were allocated in three groups in randomized controlled trial. Materials and Methods: The three groups received either port site infiltration, US-guided bilateral ESP block (ESP group), or OSTAP (OSTAP group) with bupivacaine hydrochloride 0.25%. Statistical Analysis: Postoperative 24 h Morphine consumption, visual analogue scale (VAS), the intraoperative fentanyl (μg) and equivalent morphine dose in the recovery unit were recorded and analyzed using one-way analysis of variance. Results: The mean 24-h morphine consumption was statistically significant between groups ( P < 0.001), but it was insignificant between ESP and OSTAP ( P = 0.173). Median (range) and interquartile range of intraoperatively consumed fentanyl showed significance between the three groups ( P < 0.001). There was insignificance between ESP block Group II and OSTAP block Group III ( P = 0.95) by post hoc analysis. The mean values of VAS at both rest and movement of the control group were significantly higher than the ESP block group at 6 and 12 h postoperative. Conclusion: Bilateral US-guided ESP block was found to be as effective as bilateral US OSTAP block. There was more decrease in intraoperative rescue fentanyl, PACU morphine analgesia, 24-h morphine, and pain assessment score in both groups than the control port-site infiltration group. Clinical trial registration number: NCT03398564.
BackgroundStudents’ perceptions of their learning environment, by defining its strengths and weaknesses, are important for continuous improvement of the educational environments and curriculum. Therefore, the aim of this study was to explore students’ perceptions of their learning environment, among medical students in Malaysia. Various aspects of the education environment were compared between year levels and sex.MethodsThis cross-sectional study was conducted at the Management and Science University, Shah Alam, Malaysia in 2012. A total number of 438 medical students participated in this study, and the response rate was 87.6%. Data were analyzed using SPSS. Comparisons of the mean scores of Dundee Ready Education Environment Measure (DREEM) subscales were calculated. The t-test was used to determine statistically significant differences.ResultsThe majority of the study participants were female, Malay, and from year 3 (68.7%, 65.3%, and 55.7%; respectively). Analysis of each of the 50 items of the DREEM inventory showed that 47 items scored ranged between 2.00 and 3.00, and three items scored below 2.00. These were identified as problem areas in this medical school that are required to be critically addressed. The overall score showed that the medical students’ perceptions were positive. The students’ perception toward educational environment was positive for all five DREEM subscales.ConclusionThe study found that, in general, the perceptions of the participants about the learning environment were positive. Nevertheless, the study also found there is a need for curriculum improvement in this school and identified priority areas for such improvement.
Background and Aims:Intraperitoneal local anesthetic is an effective analgesic approach in laparoscopic appendectomy in adults. The aim of the study was to compare the postoperative pain when intraperitoneal bupivacaine is administered alone versus the addition of dexmedetomidine to it in children undergoing a laparoscopic appendectomy.Methods:In this prospective randomized trial, 52 children were randomly allocated to Group B who received intraperitoneal bupivacaine 0.25% (2 mg/kg) or Group BD who received intraperitoneal bupivacaine 0.25% (2 mg/kg) plus dexmedetomidine (1 mcg/kg) for postoperative analgesia in children undergoing laparoscopic appendectomy. Postoperative pethidine consumption at day 1 was recorded and considered the primary outcome of the study. Patients were evaluated for pain scores at 0, 2, 4, 6, 12, and 24 h, time to first request of pethidine, sedation scores at 0, 2, 4, and 6 h, length of hospital stay, and parents’ satisfaction. Chi-square, Fisher's exact, Student's t-test, and Mann–Whitney U-tests were used for analysis.Results:Postoperative visual analog scale scores were lower in Group BD at 2, 4, and 6 h (mean = 3, 3, 3, respectively) compared with Group B (mean = 4, 5, 4, respectively) (P < 0.05). Patients in Group BD had more sedation scores at 0, 2, and 4 h (P < 0.05), longer time to first rescue analgesia (P = 0.03), lesser rescue analgesic consumption (P = 0.02), shorter length of hospital stay (P = 0.02), and higher parents’ satisfaction (P = 0.01).Conclusion:Adding dexmedetomidine to intraperitoneal bupivacaine provides adequate postoperative analgesia in children undergoing laparoscopic appendectomy.
