Neuromuscular Blockade and Reversal Practice Variability in the Outpatient Setting: Insights From US Utilization Patterns

BACKGROUND

Neuromuscular blockade (NMB) is a critical part of many surgical procedures. Data on practice patterns of NMB agents (NMBAs) and NMB reversal in recent years in the US ambulatory surgical care setting are limited.

METHODS

This retrospective analysis of US adult outpatients was conducted using the Premier Healthcare Database. We describe anesthesia practice trends in NMB management and assess the association of patient, procedural, and site characteristics with NMB reversal approach using multivariable logistic regression.

RESULTS

Approximately 5.2 million outpatient surgical encounters involving NMB and 4.6 million involving rocuronium or vecuronium between January 2014 and June 2019 were included. Following the introduction of sugammadex to US clinical practice (~2016), there was an increased use of rocuronium or vecuronium and a decrease in succinylcholine alone. Before 2016, NMB was pharmacologically reversed with neostigmine in approximately two-thirds of outpatient encounters. Over time, active reversal increased; by 2019, 42.3% and 36.0% of encounters were reversed by neostigmine and sugammadex, respectively, with 21.7% undergoing spontaneous recovery. Choice of NMBA (rocuronium or vecuronium alone), time since 2016, obesity, peripheral vascular disease, and procedures on the digestive, ocular, and female genital systems (vs musculoskeletal procedures) were independently and positively associated with pharmacologic reversal (versus spontaneous reversal). Conversely, advanced age; Western geography; and cardiovascular, endocrine, hemic/lymphatic, respiratory, and ear, nose, and throat procedures were independently and negatively associated with pharmacologic reversal of NMB.Among pharmacologic reversals, time since 2016 was positively and independently associated with sugammadex compared with neostigmine (odds ratios [ORs], ranged from 1.8 in 2017 to 3.2, P < .0001 in 2019). Those administered rocuronium or vecuronium without succinylcholine, with increased age and history of certain comorbidities, and those undergoing ocular or respiratory procedures (compared with musculoskeletal) were positively associated with reversal with sugammadex and endocrine procedure negatively and independently associated with reversal with sugammadex. There was variability in the association of several factors with NMB reversal choices by geographic region, particularly in patients' race, ethnicity, and size of affiliated hospital.

CONCLUSIONS

Overall, active pharmacological reversal of NMB increased in US adult outpatients following the introduction of sugammadex, although there remains significant practice variability. The multifactorial relationship between patient-, procedural-, and environmental-level characteristics and NMB management is rapidly evolving. Additional research on how these anesthesia practice patterns may be impacted by the shift to the ambulatory care setting and how they may impact patient outcomes and health disparities is warranted.

Ambulatory surgery for cancer patients: current controversies and concerns

PURPOSE OF REVIEW

This review aims to describe the main concerns and controversies of ambulatory surgery in cancer patients while providing an overview of ambulatory cancer anaesthesia.

RECENT FINDINGS

Cancer patients can undergo a variety of ambulatory surgeries. The introduction of robotic approach and the implementation of enhanced recovery programmes have allowed patients to avoid hospital admissions after more complex or invasive surgeries. In this context, the anaesthesiologist plays a key role in ensuring that the ambulatory surgical centre or the hospital-based ambulatory department is equipped for the perioperative challenges of the cancer population. Cancer patients tend to be older and with more comorbidities than the general population. In addition, these individuals may suffer from chronic conditions solely because of the cancer itself, or the treatment. Consequently, frailty is not uncommon and should be screened on a routine basis. Regional analgesia plays a key role in the provision of opioid-sparing multimodal analgesia.

SUMMARY

Neither regional anaesthesia or general anaesthesia have proven to affect the long-term oncological outcomes of cancer patients undergoing ambulatory surgery. In addition, there is insufficient evidence to suggest the use of total intravenous anaesthesia or inhalational anaesthesia over the other to decrease cancer recurrence.

Pharmacological intervention for ambulatory surgery: A protocol for systematic review and network meta-analysis

BACKGROUND

We aim to perform a network meta-analysis (NMA) to quantify and rank-order the efficacy and safety of analgesic medications for ambulatory surgery.

METHODS

We will search MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and Google Scholar databases to identify all randomized controlled trials (RCTs) of analgesics, beginning from their inception to February 2020. The primary endpoints will be pain score measured using a visual analog scale (VAS) or a numerical rating scale (NRS) at 3 different time points: Phase I recovery, phase II recovery, and recovery at home. Adverse events, including nausea, vomiting, headache, dizziness, arrhythmia, and respiratory depression, will be also assessed.We will conduct NMA and use surface under the cumulative ranking curve (SUCRA) values and rankograms to present the hierarchy of analgesic medication. A comparison-adjusted funnel plot will be used to assess the presence of small study effects. The quality of the included studies will be assessed using the risk of bias tool 2.0. All statistical analyses will be performed using Stata SE version 15.0.

RESULTS

The results of this systematic review and NMA will be published in a peer-reviewed journal.

CONCLUSION

This systematic review and NMA will provide comprehensive and convincing evidence regarding analgesic medication for pain after ambulatory surgery.

Post Ambulatory Discharge Follow-up Using Automated Text Messaging

Ambulatory surgery has grown to be the most common procedure in developed countries. Efficient quality of care and safety often require calling patient at day one after outpatient surgery to check patient's recovery and search for complications. This increasing flow in same day surgery centres motivates the use of automatic systems to contact patients. The overall objective of this study was to evaluate automated software sending text messages (TM) to patients at day 1 after ambulatory surgery compared to classical phone calls. This prospective study took place in Rennes Teaching Hospital, France, from June 1st, 2015 to December 15th, 2016. All patients owning a mobile phone were included, adults and children by means of their parents. The primary end point was the rate of successfully contacted patients, compared to usual phone calls in 2014. In cases of no response or an abnormal response, an automatic alert was sent to the ambulatory unit. Within the 7246 patients included, response rate to TM was significantly higher than response to phone calls in 2014 (87% vs 57%, respectively p < 0.0001). Most patients (85%) responded in less than 60 min. The TM algorithm detected 36% alerts (12% for lack of response to TM and 24% for TM's content). The total of reached patients' rate with TM and then phone call after an alert was 90%. Post ambulatory discharge follow-up using automated TM was successfully and easily experienced as more patients were contacted.

Opioid-Free Total Intravenous Anesthesia Improves Postoperative Quality of Recovery after Ambulatory Gynecologic Laparoscopy

Background:

Gynecological laparoscopic surgery is commonly performed on an ambulatory basis under general anesthesia. The postoperative quality of recovery (QOR) should be considered one of the principal endpoints after ambulatory surgery. Total intravenous anesthesia (TIVA) with opioids is known to improve postoperative QOR after ambulatory surgery. However, opioids can be associated with an increased incidence of postoperative complications, which can affect postoperative QOR. The primary aim of this study was to compare the patient recovery using the QOR-40 at 24 h postoperative in ambulatory gynecological laparoscopy between opioid-free (OF) TIVA and opioid-based TIVA.

Settings and Design:

A prospective, randomized, controlled, comparative study was conducted at the day surgery center.

Patients and Methods:

Eighty females were included in the study. They were randomized into two equal groups: OF TIVA group with dexmedetomidine and propofol or opioid-based TIVA (O) group with fentanyl and propofol. The primary outcome was QOR-40 at 24 h postoperative, and the secondary outcomes were postoperative numerical rating scale (NRS), time to first rescue analgesia, number of rescue tramadol analgesia, and the incidence of postoperative nausea and vomiting.

Results:

A statistically significant difference in total QOR-40 score at 24 h postoperative was observed between the groups (median [range] QOR-40 of 182.0 [164.0–192.0] in the OF TIVA group and 170.0 [156.0–185.0] in the O group; P = 0.03). OF group had significantly lower time to first rescue analgesia, maximum NRS pain scores, number of rescue tramadol analgesia, and ondansetron use.

Conclusions:

OF TIVA significantly improves postoperative QOR in patients undergoing ambulatory gynecological laparoscopic surgery.

Patient quality of recovery on the day of surgery after propofol total intravenous anesthesia for vitrectomy: A randomized controlled trial

BACKGROUND

Vitrectomy under general anesthesia is considered as a candidate for ambulatory surgery. An anesthetic method with high quality of postoperative recovery should be selected for successful ambulatory surgery. We thus compared quality of postoperative recovery on the day of vitrectomy using the Quality of Recovery (QoR)-40 questionnaire between propofol total intravenous anesthesia (propofol group) and desflurane inhalation anesthesia (desflurane group) as the 2 representative anesthetic methods.

METHODS

Eighty-four patients (20-80 years old) undergoing elective vitrectomy under general anesthesia were randomized into 2 groups. The propofol group received propofol and remifentanil using effect-site target-controlled infusion (TCI), and the desflurane group received desflurane inhalation and remifentanil using effect-site TCI. We assessed quality of recovery at 6 hours after surgery through interviews using the QoR-40 questionnaire. We also collected data related to recovery and complications during emergence and recovery period.

RESULTS

The median of QoR-40 score on the day of surgery was significantly higher in the propofol group than that in the desflurane group (181.0 vs 169.5, respectively; P = .033). In particular, propofol group had significantly higher scores for physical comfort and physical independence dimensions. The amount of remifentanil administered was significantly higher, and the emergence time was significantly longer in propofol group. However, there were no significant differences in other complications between the 2 groups.

CONCLUSIONS

Propofol total intravenous anesthesia provided significantly better quality of recovery on the day of surgery than desflurane inhalation anesthesia.

Clinical Interest and Economic Impact of Preoperative SMS Reminders before Ambulatory Surgery: A Propensity Score Analysis

Patient contact by telephone the day before ambulatory surgery is considered as a best practice. The Short Message Service (SMS) could be a suitable alternative. The objective of this prospective study was to evaluate the interest of preoperative instruction (PI) reminders by SMS compared to telephone calls. This was a prospective single center before-and-after study. Patients scheduled in ambulatory surgery were included during 2 consecutive periods of 10 weeks. The "Call" group received a telephone call for preoperative instructions (PI) and the "SMS" group received an automated protocol SMS reminder. The primary endpoint was patient compliance with PI and time of convocation. The two populations were compared with a non-inferiority hypothesis and the impact of the contact modality on compliance with the PI was assessed using a propensity score. The analysis concerned 301 patients in the Call group and 298 in the SMS group. The absence of dysfunction was observed in 75% of patients in the SMS group compared with 61% in the Call group (Risk difference: 14% [95%CI: 7-21]). The use of SMS was associated with a significant improvement in compliance with the PI (Odds ratio: 1.90 [1.48-2.42]; p < 0.0001). Patient satisfaction was similar regardless of the method of PI reminders. The automation of preoperative SMS reminders is associated with a better respect of the PI compared to the conventional calling method. This PI reminder method satisfies the majority of patients and may have a favorable financial impact.

Combination of general anesthesia and peripheral nerve block with low-dose ropivacaine reduces postoperative pain for several days after outpatient arthroscopy: A randomized controlled clinical trial

BACKGROUND

Effective methods for postoperative pain relief are an important concern in outpatient surgery. For arthroscopies we combine a single-shot peripheral nerve block using low-volume, low-concentration ropivacaine with general anesthesia. We hypothesized that the patients would have less postoperative pain and be more rapidly home ready than after general anesthesia alone.

METHODS

Patients (American Society of Anesthesiologists I-III, 18-80 years old) scheduled for outpatient arthroscopy on the upper or lower extremity were randomized to have either a combination of peripheral nerve block and general anesthesia (NB + GA, study group) or general anesthesia alone (GA, control group). The relevant nerve was localized by ultrasound and 10 mL ropivacaine 0.2% was injected. General anesthesia was with propofol and remifentanil. Numeric rating scales were used to assess pain and patient satisfaction in the recovery room, on the evening of surgery, and on the following 2 days.

RESULTS

A total of 120 patients participated in the study (NB + GA: 61; GA: 59). The percentage of patients reporting relevant pain in the recovery room were 0% versus 44% (P < 0.001), on the evening after surgery 3% versus 80% (P < 0.001), and on days 1 and 2 postsurgery 12% versus 73% and 12% versus 64% (NB + GA vs GA, respectively). Median time to home discharge was NB + GA 34.5 min (range 15-90) versus GA 55 min (20-115) (P < 0.001).

CONCLUSIONS

The combination of a peripheral nerve block with low-dose ropivacaine and general anesthesia reduced postoperative pain compared with general anesthesia alone for several days after outpatient arthroscopy. It also shortened the time to home discharge.

Evaluation and Management of Sleep Disorders in the Hand Surgery Patient

Despite posing a significant public health threat, sleep disorders remain poorly understood and often underdiagnosed and mismanaged. Although sleep disorders are seemingly unrelated, hand surgeons should be mindful of these because numerous conditions of the upper extremity have known associations with sleep disturbances that can adversely affect patient function and satisfaction. In addition, patients with sleep disorders are at significantly higher risk for severe, even life-threatening medical comorbidities, further amplifying the role of hand surgeons in the recognition of this condition.

Potent Inhalational Anesthetics for Dentistry

Nitrous oxide and the volatile inhalational anesthetics have defined anxiety and pain control in both dentistry and medicine for over a century. From curious experimentation to spectacular public demonstrations, the initial work of 2 dentists, Horace Wells and William T. G. Morton, persists to this day in modern surgery and anesthesia. This article reviews the history, similarities, differences, and clinical applications of the most popular inhalational agents used in contemporary dental surgical settings.
