Intravenous Acetaminophen Improves Outcomes After Transapical Transcatheter Aortic Valve Replacement

Efficiency and safety of pharmacotherapy for postoperative pain in cardiac surgery

Intraoperative injury with the formation of a sternotomy wound is inevitably accompanied by postoperative pain, which has a negative effect on the postoperative period and prognosis of patients. Today, moderate and severe pain affects at least half of patients in the early postoperative period after cardiac surgery. Inadequate pain relief in the early postoperative period can lead to chronic pain, which significantly reduces the quality of life of patients. The concept of multimodal analgesia with different painkillers is a priority, effective and safe technique both after cardiac surgery and in other areas of surgery. The current review article is devoted to the analysis of efficacy and safety of various drug groups for postoperative pain relief in cardiac surgery.

Preoperative Intravenous Versus Oral Acetaminophen in Outpatient Surgery: A Double-Blinded, Randomized Control Trial

PURPOSE

Preoperative acetaminophen is recognized as an effective part of the multimodal approach to perioperative pain management. The present study, conducted between April 12, 2018 and February 14, 2019, examined whether there are differences in patient-reported pain, postoperative opioid consumption, negative opioid effects, length of postanesthesia care unit stay, and patient satisfaction with pain control between patients who receive intravenous (IV) acetaminophen and patients who receive oral acetaminophen.

DESIGN

This double-blinded, randomized controlled trial was conducted among 120 patients undergoing outpatient surgery.

METHODS

Patients were randomized to receive preoperatively either intravenous (IV) acetaminophen (and oral placebo) or oral acetaminophen (and IV placebo). Results were analyzed using SPSS statistical software; statistical analyses consisted of Mann-Whitney U test, independent samples t test, and χ² test. In all analyses, a P value less than .05 was considered significant.

FINDINGS

There were no significant differences in any outcome measures based on the route of acetaminophen administration.

CONCLUSIONS

The findings of the present study support the practice of administering oral acetaminophen, as opposed to IV acetaminophen, preoperatively as part of the multimodal approach to manage postoperative pain in patients able to tolerate preoperative oral medications.

Opioid-Related Adverse Events: Incidence and Impact in Patients Undergoing Cardiac Surgery

Purpose. Opioid-related adverse drug events (ORADEs) increase patient length of stay (LOS) and health care costs. However, ORADE rates may be underreported. This study attempts to understand the degree to which ORADEs are underreported in Medicare patients undergoing cardiac surgery. Materials and Methods. The Center for Medicare and Medicaid Services administrative claims database was used to identify ORADEs in 110 158 Medicare beneficiaries who underwent cardiac valve (n = 50 525) or coronary bypass (n = 59 633) surgery between April 2016 and March 2017. The International Classification of Disease (ICD)-10 codes specifically linked to ORADEs were used to identify an actual ORADE rate, while additional ICD codes, clinically associated with butas not specific to adverse drug events were analyzed as potential ORADEs. Length of stay (LOS) and hospital daily revenue were analyzed among patients with or without a potential ORADE. Results. Among patients undergoing valve or bypass surgery, the documented ORADE rate was 0.7% (743/110 158). However, potential ORADEs may have occurred in up to 32.4% (35 658/110 158) of patients. In patients with a potential ORADE, mean LOS was longer (11.4 vs 8.2 days; P < .0001) and mean Medicare revenue/day was lower ($4016 vs $4412; P < .0001). The mean net difference in revenue/day between patients with and without an ORADE varied between $231 and $1145, depending on the Diagnosis-Related Group analyzed. Conclusions. ORADEs are likely underreported following cardiac surgery. ORADEs can be associated with increased LOS and decreased hospital revenue. Understanding the incidence and economic impact of ORADEs may expedite changes to postoperative pain management. Adopting multimodal pain management strategies that reduce exposure to opioids may improve outcomes by reducing complications, side effects, and health care costs.
