ABSTRACT
BACKGROUND: Transvaginal oocyte retrieval is frequently followed by adverse events related to anesthesia and the procedure. Some research showed that transcutaneous electrical acupoint stimulation (TEAS) can relieve intraoperative pain and postoperative nausea. OBJECTIVE: This study examined whether TEAS can alleviate pain and relieve adverse symptoms after oocyte retrieval. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: Altogether 128 patients were randomly divided into the TEAS group and the mock TEAS group. The two groups received a 30-minute-long TEAS or mock TEAS treatment that began 30 min after oocyte retrieval. MAIN OUTCOME MEASURES: The primary outcome was the visual analog scale (VAS) pain score. Secondary outcomes were pressure pain threshold, McGill score, pain rating index (PRI), present pain intensity (PPI), VAS stress score, VAS anxiety score, and postoperative adverse symptoms. RESULTS: The baseline characteristics of the two groups were comparable (P > 0.05). The VAS pain scores of the TEAS group were lower than those of the mock TEAS group at 60 and 90 min after oocyte retrieval (P < 0.05). The McGill score, PRI and PPI in the TEAS group were significantly lower than those in the control group at 60 min after oocyte retrieval (P < 0.05). However, the two groups had equivalent beneficial effects regarding the negative emotions, such as nervousness and anxiety (P > 0.05). The TEAS group was superior to the mock TEAS group for relieving postoperative adverse symptoms (P < 0.05). CONCLUSION: TEAS treatment can relieve postoperative pain and postoperative adverse symptoms for patients undergoing oocyte retrieval.

Nicotine is a significant evaluation index of tobacco and its related products' quality, but nicotine overdose can pose serious health hazards and cause addiction and dependence, thus it can be seen that it is necessary to find suitable and efficient detection methods to precisely detect nicotine in diverse samples and complex matrices. In this review, an updated summary of the latest trends in pretreatment and analytical techniques for nicotine is provided. We reviewed various sample pretreatment methods, such as solid phase extraction, solid phase microextraction, liquid phase microextraction, QuEChERS, etc., and diverse nicotine assay methods including liquid chromatography, gas chromatography, electrochemical sensors, etc., focusing on the developments since 2015. Furthermore, the recent progress in the applications and applicability of these techniques as well as our prospects for future developments are discussed.HighlightsUpdated pretreatment and analysis methods of nicotine were systematically summarized.Microextraction and automation were main development trends of nicotine pretreatment.The introduction of novel materials added luster to nicotine pretreatment.The evolutions of ion source and mass analyzer were emphasized.
