The Physiological Effects, Including Risks and Potential Benefits, of Cannabis for Patients Undergoing Elective Orthopedic Procedures.

Given the evolving regulations regarding and availability of cannabis in the United States, physicians should understand the risks and benefits associated with its use. Patients are interested in learning about the use of cannabis for the management of orthopedic pain and any potential risks associated with it when undergoing elective surgery. Edible and topical cannabis products appear to have fewer side effects than inhaled cannabis products. A review of the literature was performed regarding different modes of administration and their related risks and potential benefits specifically regarding perioperative concerns for elective orthopedic procedures. Larger studies are necessary to further determine the efficacy, safety, and side effect profile of cannabis. [Orthopedics. 2021;44(3):e314-e319.].

Paracervical blocks facilitate timely brachytherapy amidst COVID-19.

PURPOSE: The COVID-19 pandemic presents serious challenges for brachytherapists, and in the time-sensitive case of locally advanced cervical cancer, the need for curative brachytherapy (BT) is critical for survival. Given the high-volume of locally advanced cervical cancer in our safety-net hospital, we developed a strategy in close collaboration with our gynecology oncology and anesthesia colleagues to allow for completely clinic-based intracavitary brachytherapy (ICBT). METHODS AND MATERIALS: This technical report will highlight our experience with the use of paracervical blocks (PCBs) and oral multimodal analgesia (MMA) for appropriately selected cervical ICBT cases, allowing for completely clinic-based treatment. RESULTS: 18 of 19 (95%) screened patients were eligible for in-clinic ICBT. The excluded patient had significant vaginal fibrosis. 38 of 39 intracavitary implants were successfully transitioned for entirely in-clinic treatment utilizing PCBs and oral MMA (97% success rate). One case was aborted due to inadequate analgesia secondary to a significantly delayed case start time (PO medication effect diminished). 95% of patients reported no pain at the conclusion of the procedure. The median (IQR) D2cc for rectum and bladder were 64.8 (58.6-70.2) Gy and 84.1 (70.9-89.4) Gy, respectively. Median (IQR) CTV high-risk D90 was 88.0 (85.6-89.8) Gy. CONCLUSIONS: In a multidisciplinary effort, we have successfully transitioned many ICBT cases to the clinic with the use of PCB local anesthesia and oral multimodality therapy in direct response to the current pandemic, thereby mitigating exposure risk to patients and staff as well as reducing overall health care burden.

Gabapentin as an adjunct to paracervical block for perioperative pain management for first-trimester uterine aspiration: a randomized controlled trial.

BACKGROUND: Pain management approaches during uterine aspiration vary, which include local anesthetic, oral analgesics, moderate sedation, deep sedation, or a combination of approaches. For local anesthetic approaches specifically, we continue to have suboptimal pain control. Gabapentin as an adjunct to pain management has proven to be beneficial in gynecologic surgery. We sought to evaluate the impact of gabapentin on perioperative pain during surgical management of first-trimester abortion or early pregnancy loss with uterine aspiration under local anesthesia. OBJECTIVE: We hypothesized that adding gabapentin to local anesthesia will reduce perioperative and postoperative pain associated with uterine aspiration. Secondary outcomes included tolerability of gabapentin and postoperative pain, nausea, vomiting, and anxiety. STUDY DESIGN: We conducted a randomized double-blinded placebo-controlled trial of gabapentin 600 mg given 1 to 2 hours preoperatively among subjects receiving a first-trimester uterine aspiration under paracervical block in an outpatient ambulatory surgery center. There were 111 subjects randomized. The primary outcome was pain at time of uterine aspiration as measured on a 100-mm visual analog scale. Secondary outcomes included pain at other perioperative time points. To assess changes in pain measures, an intention to treat mixed effects model was fit with treatment groups (gabapentin vs control) as a between-subjects factor and time point as a within-subjects factor plus their interaction term. Because of a non-normal distribution of pain scores, the area under the curve was calculated for secondary outcomes with comparison of groups utilizing Mann-Whitney U tests. RESULTS: Among the 111 randomized, most subjects were Black or African American (69.4%), mean age was 26 years (±5.5), and mean gestational age was 61.3 days (standard deviation, 14.10). Mean pain scores at time of uterine aspiration were 66.77 (gabapentin) vs 71.06 (placebo), with a mean difference of -3.38 (P=.51). There were no significant changes in pain score preoperatively or intraoperatively. Subjects who received gabapentin had significantly lower levels of pain at 10 minutes after surgery (mean difference [standard error (SE)]=-13.0 [-5.0]; P=.01) and 30 minutes after surgery (mean difference [SE]=-10.8 [-5.1]; P=.03) compared with subjects who received placebo. Median nausea scores and incidence of emesis pre- and postoperatively did not differ between groups. Similarly, anxiety scores did not differ between groups, before or after the procedure. At 10 and 30 minutes after the procedure, most participants reported no side effects or mild side effects, and this did not differ between groups. CONCLUSION: Preoperative gabapentin did not reduce pain during uterine aspiration. However, it did reduce postoperative pain, which may prove to be a desired attribute of its use, particularly in cases where postoperative pain may be a greater challenge.

Marijuana, Lower Urinary Tract Symptoms, and Pain in the Urologic Patient.

OBJECTIVE: To describe marijuana's clinical role for urologic symptoms. METHODS: Studies related to marijuana, voiding dysfunction, lower urinary tract symptoms (LUTS), and pain through January 2019 from PubMed were evaluated for relevance and quality. RESULTS: Forty-eight studies were reviewed. Cannabinoids have mixed efficacy for neurogenic LUTS and little evidence for non-neurogenic LUTS, chronic non-cancer-related and perioperative pain. For cancer-related pain, high-level studies demonstrate cannabinoids are well-tolerated with unclear benefit. CONCLUSION: Cannabinoids appear well-tolerated in the short-term, but their efficacy and long-term impact is unproven and unknown in urologic discomfort. Cannabinoids for urologic symptoms should be further explored with well-designed randomized controlled trials.

High Patient Satisfaction With Local Anesthesia and Light Sedation in a Novel Fast-Track Setup for Sacrospinous Fixation.

OBJECTIVES: Simple prolapse operations can be performed using local anesthesia. However, this has not been the case for advanced pelvic organ prolapse operations. The aim of this study was to investigate the patient-reported feasibility and acceptability of local anesthesia and light sedation for sacrospinous fixation (SSF). METHODS: This is a prospective observational study on 105 women who underwent SSF in a public outpatient setting from April 2016 to October 2017. They received infiltration anesthesia with mepivacaine or lidocaine together with a pudendal nerve block with Marcaine. Local anesthesia was supplemented by intravenous light sedation and pain reliever. A Local Anesthetic Intraoperative Experience Questionnaire was used to evaluate patient experience. RESULTS: One patient was converted to general anesthesia. Eighty-eight women answered the questionnaires. Ninety-nine percent defined themselves as satisfied or very satisfied with the anesthesia. Little or no pain during the operation was reported by 92% and 92% would choose the same type of anesthesia again. No adverse effect of the anesthetic procedure was observed. The median (range) admission time was 12 (4.5-48) hours, and 81% of the patients could be discharged on the day of surgery. At follow-up after 8 weeks and 6 months, no patients reported adverse events to the anesthesia. CONCLUSIONS: The SSF can be performed using local anesthesia and light sedation with high degree of patient satisfaction. These preliminary data indicate that the concept of ambulatory surgery might be implemented more widely if the use of local anesthesia is also applied to more advanced surgical procedures.

Managing Procedural Pain in the Neonate Using an Opioid-sparing Approach.

PURPOSE: Pain in the neonate is often challenging to assess but important to control. Physicians often must balance the need for optimal pain control with the need to minimize oversedation and prolonged opioid use. Both inadequate pain control and overuse of opioids can have long-term consequences, including poor developmental outcomes. The aim of this review is to introduce a comprehensive approach to pain management for physicians, nurses, and surgeons caring for critically ill neonates, focusing on nonopioid alternatives to manage procedural pain. FINDINGS: After review, categories of opioid-sparing interventions identified included (1) nonopioid pharmacologic agents, (2) local and regional anesthesia, and (3) nonpharmacologic alternatives. Nonopioid pharmacologic agents identified for neonatal use included acetaminophen, NSAIDs, dexmedetomidine, and gabapentin. Local and regional anesthesia included neuraxial blockade (spinals and epidurals), subcutaneous injections, and topical anesthesia. Nonpharmacologic agents uniquely available in the neonatal setting included skin-to-skin care, facilitated tucking, sucrose, breastfeeding, and nonnutritive sucking. IMPLICATIONS: The use of various pharmacologic and interventional treatments for neonatal pain management allows for the incorporation of opioid-sparing techniques in neonates who are already at risk for poor neurodevelopmental outcomes. A multifactorial approach to pain control is paramount to optimize periprocedural comfort and to minimize the negative sequelae of uncontrolled pain in the neonate.

Endonasal Infiltrative Anesthesia for Nasal Fracture Reduction.

This study investigated the use of endonasal infiltrative anesthesia for the management of pain associated with nasal bone fracture reduction. Fifty-two patients with nasal bone fractures were distributed in 2 groups. In the first group, topical endonasal anesthesia and external transcutaneous infiltrative anesthesia were employed. In the second group, endonasal infiltrative anesthesia was also added. Visual analog scale pain scores related to the different steps of the procedure were registered. The addition of endonasal infiltrative anesthesia was associated with a significant decrease (p < .05) in pain during reduction maneuvers (6.71 vs. 4.83) and nasal packing (5.18 vs. 3.46). Addition of endonasal infiltrative anesthesia is an effective method of pain reduction during nasal bone fracture treatment.

The Influence of Local Anesthesia Depth on Procedural Pain During Fluoroscopically Guided Lumbar Transforaminal Epidural Injections: A Randomized Clinical Trial.

OBJECTIVES: The aim of the study was to evaluate the influence of the depth of local anesthesia application on procedural pain during lumbar transforaminal epidural steroid injection. DESIGN: Sixty-eight patients were enrolled who were scheduled for single-level, unilateral fluoroscopically guided lumbar transforaminal epidural steroid injection. Patients were randomly allocated to receive either subcutaneous local anesthesia (group S) or deep local anesthesia (group D) for transforaminal epidural steroid injection. The data related to pain and technical performance during the procedure was compared. In addition, the incidence of injection site soreness was assessed 2 wks after transforaminal epidural steroid injection. RESULTS: Sixty-seven patients completed all assessments (group S, n = 33; group D, n = 34). There was no significant difference in procedural pain and discomfort level between the groups (P = 0.151, P = 0.183, respectively). Patients in group D showed lower behavioral pain scores (P = 0.017). There was no significant difference in the numbers of needle manipulations, fluoroscopy time, and radiation dose during the procedure between the groups. Two patients in group S and three in group D complained of injection site soreness after transforaminal epidural steroid injection for a few days, but there was no significant difference in its incidence (P = 0.667). CONCLUSIONS: Deep local anesthesia to reduce procedural pain during transforaminal epidural steroid injection seems to have no significant clinical benefit compared with conventional subcutaneous local anesthesia.

Efficacy of Chinese herbal medicine in a case of geriatric urinary tract infections with pain of episiotomy scar inflammation.

RATIONALE: Urinary tract infections (UTIs) are common infectious diseases in women. The management of patients with UTI after menopause is commonly combined with antibiotics and external application of estrogen, which could also cause drug resistance and result in poor curative effect. This study reports a case of UTI with pain of episiotomy scar inflammation for 10 years, which was successfully cured under traditional Chinese medicine (TCM) and showed no recurrence for 5 years. PATIENT CONCERNS: A female patient, aged 71 years, experienced UTIs with pain of episiotomy scar inflammation for 10 years. Under antibiotics and external application of estrogen therapy, the patient still had no significant curative effect. Therefore, he was admitted to treatment with TCM for complementary therapy. DIAGNOSIS: UTIs with pain of episiotomy scar inflammation. INTERVENTIONS: This patient was treated with Chinese herbal medicine (CHM) treatment 2 times a day for 1 year. After 1 month of CHM treatment, the patient could tolerate pain of episiotomy scar inflammation. OUTCOMES: After 2 months of CHM treatment, the follow-up urinalysis leukocyte, red blood cell, and pH showed great improvements in examination. Late follow-up was continued to November 2017, and the patient recovered stable condition without recurrence. LESSONS: In this case, successful treatment by only applying the prescription of CHM is achieved in 1 elderly woman with UTI and pain of episiotomy scar inflammation in 1 year. It is suggested that the CHM formula has a potential effect on UTI and pain from episiotomy scar inflammation when usage of antibiotics and hormones meets with poor response.

An Extension Study Using Hypnotic Suggestion as an Adjunct to Intravenous Sedation.

The effects of hypnosis/therapeutic suggestion in connection with intravenous sedation and surgery have been described in many clinical publications; however, few randomized, controlled, and blind studies have been performed in the outpatient area. The original study published in 2010 aimed to evaluate the use of hypnosis/therapeutic suggestion as an adjunct to intravenous sedation in patients having third molar removal in an outpatient setting. The patients were randomly assigned to a treatment or control group. The treatment group listened to a rapid conversational induction and therapeutic suggestions via headphones throughout the entire surgical procedure along with a standard sedation dose of intravenous anesthetic. The control group received intravenous anesthesia but listened to only music without any hypnotic intervention. The current replication study addressed several of the limitations of the original. Sample size was increased and selection of participants from a different geographic area in Pennsylvania. Intra-operative propofol administration, patient post-operative pain ratings, and post-operative prescription pain reliever consumption were all significantly reduced in the treatment compared to the control group. Implications of these results are discussed.
