The Benefits of Local Anesthesia Used in Mastectomy Without Reconstruction.

BACKGROUND: The opioid epidemic has driven renewed interest in local anesthesia to reduce postoperative opioid use. Our objective was to determine if local anesthesia decreased hospital pain scores, oral morphine equivalents (OME), length of stay (LOS), and nausea/vomiting. METHODS: Single institution retrospective study of females who underwent mastectomy without reconstruction. RESULTS: Overall, 712 patients were included; 63 (8.8%) received bupivacaine (B), 512 (72%) liposomal bupivacaine (LB), and 137 (19%) no local. 95% were discharged on POD1. Liposomal bupivacaine use increased from 2014 to 2019. Additional factors associated with use of local regimen were surgeon and extent of axillary surgery. Fewer patients used postop opioids during their hospital stay if any local was used compared to none (76 vs 88%; 0.003). Compared to none, local had shorter mean PACU LOS (95 vs 87 min; P = .02), lower mean intraoperative-OME (96 vs 106; P < .001), and lower mean postoperative OME/hr (1.4 vs 1.8 P = .001). Multivariable analysis (MVA) showed lower OME/hr with LB compared to B and none (P = .002); this translates to 22 mg and 30 mg of oxycodone in a 24-hr period, respectively. MVA showed lower POD1 pain scores with LB relative to none (P = .049). Local did not impact nausea/emesis. CONCLUSION: Local anesthesia was superior to no local in several measures. However, a consistent benefit of a specific local anesthetic agent was not demonstrated (LB vs B). A prospective study is warranted to determine the optimal local regimen for this cohort and further inform clinical relevance.

Caffeine supplementation as part of enhanced recovery after surgery pathways: a narrative review of the evidence and knowledge gaps.

Caffeine is used daily by 85% of United States adults and caffeine withdrawal is a major cause of perioperative headache. Studies have shown that caffeine supplementation in chronic caffeinators reduces the incidence of perioperative headache. This narrative review discusses the perioperative implications of caffeine withdrawal and outlines the benefits of and strategies of caffeine supplementation in the perioperative period. It is time to "wake up and smell the coffee" on integration of caffeine into established enhanced recovery after surgery protocols as a mechanism to consistently provide perioperative caffeine replacement.

RéSUMé: La caféine est utilisée quotidiennement par 85 % des adultes aux États-Unis, et le sevrage de la caféine constitue une cause majeure de céphalées périopératoires. Des études ont montré que la supplémentation en caféine chez les grands buveurs de café réduisait l'incidence des céphalées périopératoires. Ce compte rendu narratif discute des implications périopératoires du sevrage de la caféine et décrit les avantages et les stratégies de la supplémentation en caféine en période périopératoire. Il est temps de « se réveiller à l'odeur du café ¼ quant à l'intégration de la caféine dans les protocoles de récupération rapide après la chirurgie en tant que mécanisme pour procurer de façon systématique un subsitut périopératoire à la caféine.

Intermittent bolus versus continuous infusion techniques for local anesthetic delivery in peripheral and truncal nerve analgesia: the current state of evidence.

Manually delivered intermittent bolus (MIB) and programmable intermittent bolus (PIB), alternatives to continuous infusion (CI), involve administering a set volume of solution at a set interval of time. The benefits of intermittent bolus techniques in truncal and peripheral nerve blockade (TPNB) are unclear, and studies have largely demonstrated conflicting results. Using MEDLINE, Embase, Google Scholar, and the Cochrane Library, we conducted an evidenced-based review of published randomized controlled trials comparing intermittent bolus and CI methods in TPNB. In total, 13 randomized controlled trials were identified and evaluated. Outcomes data addressed in these studies included assessments of pain, opioid and local anesthetic consumption, patient satisfaction, adverse events, and physical therapy metrics. The overall quality of current evidence was found to be low given the small sample sizes, heterogeneity of data, and the variations in intermittent bolus techniques between studies. At this time, we found limited supportive data to endorse MIB or PIB over CI in TPNB. While unable to provide data-driven conclusions for local anesthetic delivery methods at this time, we propose that future studies and quantitative analysis between techniques should be on an anatomic, site-specific basis, with greater focus on evaluation of opioid use, adverse events, patient satisfaction, and rehabilitative metrics.

Spice: a legal marijuana equivalent.

Spice, an herbal mixture containing synthetic cannabinoids, is a legal drug increasingly abused by adolescents and young adults for its narcotic-like effects. A paucity of English language literature exists on the clinical effects of Spice use. A case report of substance-induced psychosis and a summary of available literature follows later.

Local and paravertebral block anesthesia for outpatient elective breast cancer surgery.

Most breast cancer operations in the United States are performed with the patient given general anesthesia. We retrospectively reviewed our prospective breast cancer database to determine the percentage of patients who underwent breast cancer operations with either local or paravertebral block regional anesthesia from January 1 through June 30, 2008. Fifty-two of 70 patients (74%) were able to undergo breast cancer surgery with local or paravertebral block regional anesthesia. Operations included mastectomy, full axillary dissections, and expander or implant reconstruction. There were no conversions to general anesthesia and no unplanned overnight admissions. Only 5 of 52 patients (10%) undergoing surgery with local or paravertebral block regional anesthesia developed postoperative nausea or vomiting. We conclude that most elective outpatient breast cancer surgery operations can be performed with the patients given local or regional anesthesia.
