17; confidence interval [CI], 1.89-2.49; P less then .001) following surgery compared to nonopioid-only users. When compared to traditional opioid use, tramadol use was associated with decreased risk of subsequent 90-day minor medical complications (OR, 0.75; CI, 0.62-0.90; P = .002), emergency department visits (OR, 0.70; CI, 0.57-0.85; P less then .001), and prolonged narcotic use (OR, 0.43; CI, 0.37-0.49; P less then .001). Traditional opioid use significantly increased length of stay by 0.20 days (P = .001) when compared to tramadol use. Conclusion Preoperative tramadol use is associated with prolonged opioid use following THA but is not associated with other postoperative complications. Patients taking tramadol preoperatively appear to have a lower risk of postoperative complications compared to patients taking traditional opioids preoperatively.Background Recently, the practice of ordering routine postoperative laboratory tests in primary total hip arthroplasty (THA) has been challenged. read more This study aimed to evaluate the utility of routine postoperative laboratory tests after primary elective THA in an Asian population and identify the risk factors associated with abnormal postoperative laboratory test-related intervention. Methods We retrospectively reviewed 395 consecutive patients who underwent primary elective THA at a single tertiary academic center. Patient clinical information and laboratory test results were collected for analysis. Results A total of 349 (88.4%) patients had abnormal postoperative laboratory test results; most patients had anemia and hypoalbuminemia. Twenty-seven (6.8%) patients received clinical intervention. Of the 307 (77.7%) patients with postoperative anemia, 7 patients received blood transfusion. Factors associated with transfusion were female gender, low body mass index, long operation time, and low preoperative hemoglobin levels. Of the 149 (37.7%) patients with postoperative hypoalbuminemia, 16 received albumin supplementation. Factors associated with albumin supplementation were female gender, long operation time, and low preoperative albumin levels. Although 36 patients had abnormal postoperative creatinine, only 1 patient required specialist consultation. For electrolyte abnormalities, hyponatremia was noted; however, no patient received sodium supplementation. Moreover, 14 patients developed hypokalemia, of which 6 required potassium supplementation; 163 patients had hypocalcemia, of which 2 received calcium supplementation. Conclusion Routine laboratory tests after primary elective THA are unnecessary for most of the patients in modern clinical practice. However, for those with identified risk factors, postoperative laboratory tests still should be performed.The COVID-19 pandemic is an extraordinary global situation, and all countries have adopted their own strategies to diminish and eliminate the spread of the virus. All measures are in line with the recommendations provided by the World Health Organization. Scientific societies, such as the European Society for Human Reproduction and Embryology and American Society for Reproductive Medicine, have provided recommendations and guidance to overcome and flatten the growing curve of infection in patients who undergo IVF treatments. Although there is as yet no evidence that the virus causing COVID-19 might have negative effects on IVF outcomes, fertility treatments have been postponed in order to support healthcare systems by avoiding placing them under additional stress. The possibility of the virus affecting sperm function and egg performance cannot be excluded. In addition, an indirect effect of the virus on gametes and embryos during their manipulation cannot be ruled out. This commentary aims to provide some ideas on the possible effect of the virus on gametes and embryos, as well as how it could affect the normal functioning of the embryology laboratory.The outbreak of 2019 novel coronavirus disease (COVID-19) has become a major pandemic threat worldwide. Such a public health emergency can greatly impact various aspects of people's health and lives. This paper focuses on its potential risks for reproductive health, including the reproductive system and its functioning, as well as gamete and embryo development, which could be affected by the virus itself, drug treatments, chemical disinfectants and psychological effects related to panic during the COVID-19 outbreak.Research question Is intracytoplasmic sperm injection (ICSI) operator experience associated with fertilization, usable blastocyst development and sustained implantation rates (SIR) when at least two embryologists carry out ICSI for a single cohort of oocytes? Design A retrospective cohort study of all IVF/ICSI cycles at a single large infertility centre between 2008 and 2018. Cycles were included if a cohort of oocytes was split between two embryologists for ICSI. The embryologist's experience of ICSI was used to evaluate laboratory and clinical outcomes overall and by pairs of inseminating embryologists. Logistic regression, analysis of variance and Kruskal-Wallis testing were used where appropriate. Results Analysis of 14,362 ICSI procedures showed an association between least ICSI experience and lower mean fertilization rates (P less then 0.0001), higher odds of failed fertilization (adjusted OR 4.3; P less then 0.0001) and lower number of fertilization 'wins' per cohort (P less then 0.0001). Usable blastocyst development rates (number of usable blastocysts/number of two pronuclear zygotes) were not associated with ICSI embryologist experience (P = 0.44), but the odds of obtaining no usable blastocysts were higher (adjusted OR 1.4; P less then 0.0001) and the proportion of usable blastocyst 'wins' was lower (P = 0.0001) when embryologists with the least experience carried out ICSI. Increased ICSI experience was associated with higher mean SIR (P less then 0.0001). Laboratory and clinical outcomes were similar among embryologists once 1000 ICSI cycles and above were carried out. Conclusions Increased ICSI operator experience is associated with higher fertilization rates, SIR and a lower likelihood of failed fertilization and usable blastocyst development. Splitting a single oocyte cohort between more than one embryologist for ICSI is a quality-control measure that can be implemented.
