A Review of the Analgesic Benefi ts and Potential Complications Related to Epidural Corticosteroid Injections.

The Institute of Medicine has reported that greater than 115 million adults in the United States are living with some form of chronic pain. Back pain is the most prevalent and is associated with high individual morbidity and increased healthcare costs. One approach for the management of chronic back pain involves the injection of corticosteroids in the epidural space.This interventional approach requires advanced training with techniques that vary according to the level of the vertebral column where the injection is to be performed. The primary rationale for epidural steroid injection is to reduce the inflammation surrounding the spinal nerve root as it exits the neuroforamen.Injections are performed at levels that correspond most appropriately with the patient's clinical presentation,physical findings, and radiographic findings. Epidural steroid injections are considered safe and effective, and are supported by evidence for the treatment of radicular pain. Complications from epidural steroid injections are rare but can be catastrophic, including permanent disability and death. The focus of this article is to understand how technique and selection of specific corticosteroids used for epidural injection can manage chronic back and radicular pain effectively while minimizing risk that leads to unnecessary harm.

Opioid Overdose and Naloxone Kit Distribution: A Quality Assurance Educational Program in the Primary Care Setting.

PROBLEM: In 2014, there were approximately 200,000 incidents of an unintentional opioid overdose nationwide. The 2016 Centers for Disease Control and Prevention opioid prescription guidelines identified a knowledge deficit regarding opioid prescribing among primary care providers as a contributing factor to this epidemic. PURPOSE: The purpose of this quality assurance project was to provide education on opioid overdose and distribution of naloxone kits through a presentation to primary care providers at Veterans Administration facilities in the southeast region of the United States. METHODS: A convenience sampling strategy was utilized for this project. Primary care providers who prescribe opioids or care for patients at risk of an opioid-related event or death were invited to participate. A Likert scale survey was used to determine the effectiveness of the presentation. RESULTS: The results of the survey showed a potential for improving medical providers' perceptions and comfort with prescribing naloxone kits. The mean score at pretest was 32 of 50 (64%) in contrast to 42 of 50 (84%) after attending the presentation. Attending this quality assurance presentation was related to an increased awareness of naloxone kit availability and Centers for Disease Control and Prevention recommendations regarding the safe administration of opioids. CONCLUSION: This educational presentation can assist providers in identifying patients who are prescribed opioids and at risk for accidental overdose and death.

The Last State to Grant Nurse Practitioners DEA Licensure: An Education Improvement Initiative on the Florida Prescription Drug Monitoring Program.

Nurse practitioners (NPs) now have prescriptive authority for controlled substances in all 50 states in the United States. Florida, the last state to grant NPs DEA licensure, has been wrought with prescription diversion practices for a number of years as pill mills, doctor shopping, and overprescribing proliferated. Prescription Drug Monitoring Programs (PDMPs) help curb drug diversion activity and play a key role in reducing the abuse of controlled substances. The primary objective of this education improvement initiative was to increase knowledge of actively licensed NPs in the state of Florida regarding the state's PDMP. The main themes included the drug abuse problem, description and progression of the PDMP, and how to use the Florida PDMP. Upon approval from the institutional review board, this education improvement initiative gauged NP knowledge of the PDMP and main themes before and after an educational PowerPoint intervention. A pretest/posttest questionnaire was administered for assessment of all knowledge questions. One hundred forty-five NPs with active advanced registered NP licenses in Florida completed both the pretest and posttest questionnaires. Descriptive statistics and paired t tests were used for statistical significance testing. Knowledge of the PDMP and the main themes of the education improvement initiative significantly increased (p < .001) from pretest to posttest results. This education improvement initiative had positive effects for NPs on the knowledge of the Florida PDMP and the main themes. This indicated that Florida NPs are able to acquire greater comprehension of the PDMP by an education intervention.

Evaluation of postprocedure cognitive function using 3 distinct standard sedation regimens for endoscopic procedures.

The primary purpose of this investigation was to evaluate postprocedure cognitive function associated with 3 distinct standard sedation regimens used for endoscopic procedures. A secondary aim was to identify complications requiring provider interventions. Subjects scheduled for colonoscopies were approached for enrollment the day of their procedure. A convenience sample of 96 subjects was randomly assigned. Cognitive function was recorded on the day of surgery using the Mini-Mental State Examination (MMSE) and 24 and 48 hours postoperatively using the Telephone Interview of Cognitive Status (TICS). The propofol plus fentanyl group had a mean TICS score of 34.53 at 24 hours compared with 34.96 at 48 hours (P = .017). The midazolam plus fentanyl group had a mean TICS score of 34.76 at 24 hours compared with 36.26 at 48 hours (P = .004). The propofol-alone group had a mean TICS score of 35.09 at 24 hours compared with 35.98 at 48 hours (P = .924). The results of this investigation indicate that the sedation regimen of propofol alone has the least impact on postprocedure cognitive function. Additionally, the number of jaw lift interventions was significantly higher in both groups who received fentanyl.

Determining the relationship of acute stress, anxiety, and salivary alpha-amylase level with performance of student nurse anesthetists during human-based anesthesia simulator training.

Managing stress for student nurse anesthetists represents a multifaceted educational concern for anesthesia educators. Our purpose was to determine the relationship between physiologic measures of stress and performance of student nurse anesthetists during anesthesia simulator training. Following institutional review board approval, 78 students were enrolled from a nurse anesthesia program. A prospective descriptive design was used to compare baseline, acute, and recovery measurements of stress with performance scores of students during an induction and intubation sequence in a patient simulator. Performance scores were stratified into low-, moderate-, and high-performing groups based on scores received from trained observers. A statistically significant difference in physiologic measures of stress was detected between baseline and acute levels of salivary a-amylase (P = .017), heart rate (P = .003), and anxiety levels (P = .001). No significant differences were found when measures of stress were compared with performance of low, moderate, or high performers. This investigation revealed remarkable findings regarding the relationship between stress and student performance. Analysis of the descriptive statistics and means of each group suggests that low performers have increased stress and perform poorly, whereas high performers have increased stress and perform superbly, and moderate performers have modest stress and perform moderately.

Effects of guided imagery on postoperative outcomes in patients undergoing same-day surgical procedures: a randomized, single-blind study.

The purpose of this investigation was to evaluate the effects of guided imagery on postoperative outcomes in patients undergoing same-day surgical procedures. Forty-four adults scheduled for head and neck procedures were randomly assigned into 2 groups for this single-blind investigation. Anxiety and baseline pain levels were documented preoperatively. Both groups received 28 minutes of privacy, during which subjects in the experimental group listened to a guided imagery compact disk (CD), but control group patients received no intervention. Data were collected on pain and narcotic consumption at 1- and 2-hour postoperative intervals. In addition, discharge times from the postoperative anesthesia care unit (PACU) and the ambulatory procedure unit and patient satisfaction scores were collected. The change in anxiety levels decreased significantly in the guided imagery group (P = .002). At 2 hours, the guided imagery group reported significantly less pain (P = .041). In addition, length of stay in PACU in the guided imagery group was an average of 9 minutes less than in the control group (P = .055). The use of guided imagery in the ambulatory surgery setting can significantly reduce preoperative anxiety, which can result in less postoperative pain and earlier PACU discharge times.

Therapeutic modalities for the prophylactic management of postoperative nausea and vomiting.

The occurrence of postoperative nausea and vomiting (PONV) remains one of the most common complications after general anesthesia. The causes of PONV are multimodal, involving several physiologic pathways that stimulate the vomiting center, including the chemoreceptor trigger zone, the gastrointestinal tract, the vestibular system, the cerebral cortex, and the midbrain. Significant research has been published focusing on the use of different pharmacologic agents and varying anesthetic techniques to prevent and manage PONV. The addition of therapeutic modalities to the arsenal of prophylactic management techniques may decrease patient incidence of PONV by directing treatment to various pathways that stimulate the vomiting center. The purpose of this article is to review briefly the literature and discuss three therapeutic modalities for preventing PONV: perioperative oxygen administration, perioperative intravenous fluid administration, and differing fasting protocols.

Headache disability in orofacial pain patients.

OBJECTIVE: To retrospectively examine the reported history of and the disability caused by headaches in patients presenting for evaluation and treatment of orofacial pain. BACKGROUND: More than 81% of patients with the chief complaint of pain in the orofacial region concomitantly report pain in other body locations. Among the comorbidities frequently reported with orofacial pain are a variety of different headaches types, including migraines, tension type headaches, and chronic daily headaches. The extent of the disability caused by those headache complaints in a large patient population is unknown. METHODS: The Migraine Disability Assessment (MIDAS) is administered to all patients as a part of the initial assessment at the Orofacial Pain Center. This investigation is retrospectively examined the reported history of and the disability caused by headaches in patients who presented for evaluation and treatment of orofacial pain in the Orofacial Pain Center, National Naval Medical Center, Bethesda, MD, between the dates of 1 September 2003 and 1 December 2004. RESULTS: In the present study 261 (61.3%) patients reported a headache complaint and 100 (38%) fulfilled the criteria for migraine with or without aura. MIDAS scores were reported by 55.3% of 426 patients with the mean score of 23.68. There were no significant differences in MIDAS scores in relation to the presence or absence of an intracapsular disorder. Patients with masticatory and/or cervical myalgia demonstrated significantly higher MIDAS scores when compared to patients without myalgia. CONCLUSIONS: These findings clearly demonstrate the necessity for evaluation of headache and related disability in orofacial pain patients.

The addition of clonidine to bupivacaine in combined femoral-sciatic nerve block for anterior cruciate ligament reconstruction.

Clonidine has been shown to prolong sensory analgesia when given as an adjunct to peripheral nerve blocks but has not been evaluated when given in conjunction with a femoral-sciatic nerve block. The purpose of this investigation was to determine whether the addition of clonidine to a femoral-sciatic nerve block would prolong the duration of sensory analgesia in groups of patients undergoing anterior cruciate ligament (ACL) reconstruction. This prospective, randomized, double-blind investigation was performed on 64 subjects undergoing ACL reconstruction. Patients were assigned randomly to receive a femoral-sciatic nerve block using 30 mL of 0.5% bupivacaine with 1:200,000 epinephrine (control group) or 30 mL of 0.5% bupivacaine with 1:200,000 epinephrine and 1 microg/kg of clonidine (experimental group). Variables measured included demographics, timed pain intensity measurements, postoperative analgesic consumption, duration of analgesia, and patient satisfaction. No significant differences were noted between groups for pain intensity scores, duration of sensory analgesia, postoperative analgesic requirements, or overall patient satisfaction. Both groups reported minimal amounts of postoperative pain and high analgesic satisfaction scores. Based on our results, we do not recommend the addition of clonidine to a femoral-sciatic nerve block when given to facilitate postoperative analgesia in patients undergoing ACL reconstruction.

Effect of needle size on success of transarterial axillary block.

The transarterial approach to brachial plexus block is a well-established method of producing anesthesia of the upper extremity. However, it is associated with a failure rate of 20% to 30%. Failure may be secondary to the common use of a relatively long needle, which can penetrate the posterior wall of the sheath and result in inadvertent injection of the local anesthetic into the surrounding tissue. The purpose of this investigation was to compare success rates following transarterial brachial plexus block with a standard 22-gauge, 1 1/2-in, B bevel needle or a 26-gauge, 1/2-in needle. We enrolled 98 subjects scheduled for elective surgery at or below the elbow and randomized them into 2 groups. The control group received a transarterial axillary block with a standard 22-gauge, 1 1/2-in, B bevel needle, and the experimental group received a transarterial axillary block with a 26-gauge, 1/2-in needle. Success was defined as no discomfort at the time of incision. Success rates were compared using a chi 2 test, and a P value of less than .05 was considered significant. The overall success rate was significantly higher with the 26-gauge, 1/2-in needle (42/48 [88%]) than with the 22-gauge, 1 1/2-in needle (39/49 [69%]; P = .035).

Postoperative respiratory depression and unresponsiveness following epidural opiate administration: a case report.

The profound segmental antinociception that epidural opioids offer has increased their use over the last 2 decades. Though side effects may accompany the use of epidural opioids, clinicians have found that the advantages far outweigh the disadvantages. The following case report outlines a patient's postoperative course in which she experienced respiratory depression while receiving epidural opioids. The pharmacokinetics of lipophilic vs hydrophilic opioids in relation to the occurrence of respiratory depression is discussed.

Severe intraoperative hyponatremia in a patient scheduled for elective hysteroscopy: a case report.

Hysteroscopy is a minimally invasive procedure that may result in potentially disastrous complications. A hysteroscopy requires the insertion of a hysteroscope into the uterine cavity and the installation of a suitable distention medium for visualization of the endometrium. Potential risks include fluid volume overload, uterine perforation, hemorrhage, infection, and the need for immediate hysterectomy. Solutions most commonly used for distention of the uterine cavity are 1.5% glycine and sorbitol. Hypotonic, electrolyte-free distention media have the potential to be absorbed in volumes large enough to cause hyponatremia and hypervolemia, complications initially described as transurethral resection of the prostate (TURP) syndrome. Hyponatremia and hypervolemia have been associated with hysteroscopic surgical procedures. The following is a case report detailing the perioperative events of a 40-year-old woman in whom severe hyponatremia developed during an elective hysteroscopy.

Hand ischemia associated with profound hypotension and radial artery catheterization in a pediatric patient: a case report.

Direct arterial blood pressure monitoring via the radial artery is a relatively common method employed during the perioperative period. Complications attributed to radial artery catheterization are extremely rare but can include thrombosis, ischemia, infection, and aneurysm formation at the site of catheter insertion. This report describes an episode of hand ischemia in a pediatric patient. The patient experienced a brief period of hypotension secondary to blood loss. A pallor hand was noticed after the patient had been adequately resuscitated. Appropriate treatment was administered, and the patient was eventually discharged to home without any further complications.

Acute fatty liver of pregnancy: a case report.

The third trimester of pregnancy has several unique disease entities that challenge the anesthetist. Acute fatty liver of pregnancy (AFLP) is an increasingly recognized metabolic disorder found late in pregnancy. Current research estimates the incidence of AFLP at 1 per 6,659 births. Improved maternal morbidity and mortality is credited to early recognition and termination of the pregnancy. The decline in hepatic cellular activity is evident by the deterioration in metabolic, synthetic, and excretory functions of the liver. This obstetrical emergency can lead to death of both mother and child if not diagnosed in time to prevent coagulopathic complications.
