ABSTRACT
OBJECTIVE To mine and analyze adverse drug event （ADE） signals after the marketing of pazopanib and provide references for clinically safe medication. METHODS OpenVigil 2.1 data platform was used to mine ADE signals from the US FDA adverse event reporting system （FAERS） database. ADE reports of pazopanib from October 2009 to June 2022 were collected， and ADE signals were analyzed using proportional reporting ratio （PRR） method and reporting odds ratio （ROR） method in the proportional imbalance method. RESULTS A total of 16 655 ADE reports were identified with pazopanib as the primary suspect drug. Through ROR and PRR analysis， 220 ADE signals involving 19 system organ classes were identified. The top 10 ADE signals by frequency were recorded in the drug instruction. Additionally， 88 new ADE signals were discovered， mainly related to the gastrointestinal system， various investigations， and the renal and urinary system. Decreased basophil count， nail bed hemorrhage， tumor rupture， and vaginal fistula were both new ADE signals and the top 10 ADE signals by strength. CONCLUSIONS The occurrence of common ADEs （diarrhea， hair color changes， hypertension， etc.） during the use of pazopanib after marketing is generally consistent with its drug instruction； the number of reported cases for new suspected risk signals （decreased basophil count， nail bed hemorrhage， tumor rupture， and vaginal fistula， etc.） is limited， and continuous monitoring is required.
ABSTRACT
BACKGROUND:Accumulating studies have confirmed the excellent effectiveness of local infiltration analgesia, but the literature analysis is mainly limited to within 1 day after total knee arthroplasty or shorter period. OBJECTIVE:To study the effectiveness of local infiltration analgesia (LIA) at low concentration after total knee arthroplasty, and to observe the analgesic effect at rest and movement states. METHODS:Thirty patients undergoing total knee arthroplasty were randomly al ocated to control group and LIA group, receiving oral non-steroidal anti nflammatory drug (celebrex) and low concentration of ropivacaine (0.1%) for epidural analgesia. Control group was injected with 0.9%saline 150 mL, while LIA group was injected with equal volume of solution include ropivacaine 300 mg, morphine 5 mg and epinephrine 10μg. The rest pain and motion pain of patients in two groups were evaluated at 6, 12, 24, 36, 48 hours after operation by using visual analogue scale. The incidence rate and degree of nausea, vomiting, numbness and muscle weakness of the legs were observed after operation. The incision healing was also recorded. RESULTS AND CONCLUSION:Visual analogue scale pain scores in the LIA group were significantly lower than the control group at 6, 12, 24 and 36 hours at rest (P0.05). No patient appeared drowsiness, nausea, and vomiting in both groups. Two patients in each group complained of slight numbness in legs. No case influenced function exercise because of muscle weakness. Al the wounds healed and there were no incision infections in two groups. Combined with oral non-steroidal anti-inflammatory drug and low concentration of ropivacaine for epidural analgesia, the local infiltration analgesia technique in total knee arthroplasty is effective in early post-operative pain management, and produces no analgesia related adverse reactions.
ABSTRACT
Objective: To compare the effects of nicardipine and labetalol on hypertension during laparoscopic cholecystectomy.Methods:Thirty patients with hypertension undergoing selective laparoscopic cholecystectomy were randomly divided into 3 groups. The control group was only given anesthetic drugs; nicardipine group was given nicardipine 20 ?g?kg -1 ?min -1 before induction, followed by intravenous continuous infusion of nicardipine at the rate of 0.5 1.5 ?g?kg -1 ?min -1 ; labetalol group received labetalol 0.3 mg?kg -1 ?min -1 before induction followed by intravenous continuous infusion of labetalol at the rate of 10 20 ?g?kg -1 ?min -1 . Results: Statistical differences( P
