Establishing a patient centered, outpatient total joint home recovery program within an integrated healthcare system.

Outpatient total joint home recovery (HR) is a rapidly growing initiative being developed and employed at high volume orthopedic centers. Minimally invasive surgery, improved pain control and home health services have made HR possible. Multidisciplinary teams with members ranging from surgeons and anesthesiologists to hospital administrators, physical therapists, nurses and research analysts are necessary for success. Eligibility criteria for outpatient total joint arthroplasty will vary between medical centers. Surgeon preference in addition to medical comorbidities, social support, preoperative patient mobility and safety of the HR location are all factors to consider when selecting patients for outpatient total joint HR. As additional knowledge is gained, the next steps will be to establish 'best practices' and speciality society-endorsed guidelines for patients undergoing outpatient total joint arthroplasty.

Routine chest X-ray is unnecessary after ultrasound-guided central venous line placement in the operating room.

BACKGROUND: Central venous catheters (CVC) can be useful for perioperative monitoring and insertion has low complication rates. However, routine post insertion chest X-rays have become standard of care and contribute to health care costs with limited impact on patient management. METHODS: 200 patient charts who underwent pancreaticoduodenectomy with central line placement and early line removal were reviewed for clinical complications related to central line placement as well as radiographic evidence of malpositioning. A cost analysis was performed to estimate savings if CXR had not been performed across routine surgical procedures requiring central access. RESULTS: In 200 central line placements for Whipple procedures, 198 lines were placed in the right internal jugular and 2 were placed in the subclavian. No cases of pneumothorax or hemothorax were identified and 30 (15.3%) of CVCs were improperly positioned. Only 1 (0.5%) of these was deemed clinically significant and repositioned after the CXR was performed. CONCLUSION: Routine CXR consumes valuable time and resources (≅$155,000 annually) and rarely affects management. Selection should be guided by clinical factors.

Review of the evidence: best analgesic regimen for shoulder surgery.

Multimodal pain management has been advocated in patients experiencing acute pain after surgical procedures due to tissue damage and the subsequent inflammatory response. For patients undergoing shoulder surgeries, studies have definitively shown that interscalene blocks (ISBs) via single-injection or continuous infusion can reduce the total opioid consumption and can lower pain scores after surgery. In some cases, ISBs can be used as the sole anesthetic during shoulder surgeries and spare patients of receiving general anesthesia. However, clinicians should be fully aware of potential pulmonary complications of ISBs and weigh the risk-benefit ratio in patients with limited pulmonary reserve.

Workup and Management of Persistent Neuralgia following Nerve Block.

Neurological injuries following peripheral nerve blocks are a relatively rare yet potentially devastating complication depending on the type of lesion, affected extremity, and duration of symptoms. Medical management continues to be the treatment modality of choice with multimodal nonopioid analgesics as the cornerstone of this therapy. We report the case of a 28-year-old man who developed a clinical common peroneal and lateral sural cutaneous neuropathy following an uncomplicated popliteal sciatic nerve block. Workup with electrodiagnostic studies and magnetic resonance neurography revealed injury to both the femoral and sciatic nerves. Diagnostic studies and potential mechanisms for nerve injury are discussed.

Right Breast Mastectomy and Reconstruction with Tissue Expander under Thoracic Paravertebral Blocks in a 12-Week Parturient.

Paravertebral blocks are becoming increasingly utilized for breast surgery with studies showing improved postoperative pain control, decreased need for opioids, and less nausea and vomiting. We describe the anesthetic management of an otherwise healthy woman who was 12 weeks pregnant presenting for treatment of her breast cancer. For patients undergoing breast mastectomy and reconstruction with tissue expanders, paravertebral blocks offer an anesthetic alternative when general anesthesia is not desired.

Anesthetic implications of extended right hepatectomy in a patient with fontan physiology.

Patients who have undergone complete cavopulmonary anastomosis, the Fontan procedure, have passive venous blood flow from the superior and inferior vena cava into the pulmonary circulation without passing through the right ventricle. Although this procedure is an effective means of palliation, the resultant chronically increased central venous pressure, leads to several types of hepatic dysfunction including chronic congestion, cardiac cirrhosis, and even hepatocellular carcinoma. In this case report, we describe a patient with Fontan-associated hepatocellular carcinoma who successfully underwent a right hepatectomy.

An overview of cytoreductive surgery and hyperthermic intraperitoneal chemoperfusion for the anesthesiologist.

Anesthesiologists face several perioperative challenges when patients need cytoreductive surgery and hyperthermic intraperitoneal chemoperfusion. To adequately care for these patients, anesthesiologists must understand the goals and objectives of the operation in addition to having a basic knowledge of the chemotherapeutic drugs that are frequently used. Optimal anesthetic management of patients treated with cytoreductive surgery and hyperthermic intraperitoneal chemoperfusion requires control of a complex interplay of physiologic mechanisms, including hyperthermia, abdominal hypertension, electrolyte abnormalities, coagulopathies, increased cardiac index, oxygen consumption, and decreased systemic vascular resistance. As this surgery continues to gain popularity among oncologic surgeons, further studies that clearly define the chemistry, pharmacokinetics, pharmacodynamics, and end points of efficacy need to be performed to elucidate optimal perioperative management.

Asystole after orthotopic lung transplantation: examining the interaction of cardiac denervation and dexmedetomidine.

Dexmedetomidine is an α(2)-receptor agonist commonly used for sedation and analgesia in ICU patients. Dexmedetomidine is known to provide sympatholysis and also to have direct atrioventricular and sinoatrial node inhibitory effects. In rare instances, orthotopic lung transplantation has been associated with disruption of autonomic innervation of the heart. The combination of this autonomic disruption and dexmedetomidine may be associated with severe bradycardia and/or asystole. Since orthotopic lung transplant patients with parasympathetic denervation will not respond with increased heart rate to anticholinergic therapy, bradyarrhythmias must be recognized and promptly treated with direct acting beta agonists to avoid asystolic cardiac events.

Unintentional dural puncture with a Tuohy needle increases risk of chronic headache.

BACKGROUND: Neuraxial analgesia is chosen by almost half of women who give birth in the United States. Unintentional dural puncture is the most common complication of this pain management technique, occurring in 0.4% to 6% of parturients. Severe positional headaches develop acutely in 70% to 80% of these parturients. Acute postdural puncture headaches are well known, but few studies have investigated long-term sequelae. We investigated the incidence of and risk factors for chronic headache and chronic back pain in parturients who experienced unintentional dural puncture with a 17-gauge Tuohy needle compared with matched controls. METHODS: In a case control design, 40 parturients who sustained unintentional dural puncture with a 17-gauge Tuohy needle over an 18-month period and 40 controls matched for age, weight, and time of delivery were recruited by telephone and 2 validated questionnaires were administered assessing headache and back pain symptoms 12 to 24 months after delivery. RESULTS: The incidence of chronic headaches in the study group (28%) was significantly higher than in the matched controls (5%) (OR = 7, P = 0.0129). Subjects who experienced dural punctures were more likely than controls to report chronic back pain (OR = 4, P = 0.0250), but treatment with an epidural blood patch was not a risk factor for chronic back pain. CONCLUSIONS: Patients who incur unintentional dural punctures with large-gauge needles are surprisingly likely to continue to suffer chronic headaches. Treatment with an epidural blood patch does not enhance the risk of chronic back pain. The pathophysiology underlying these symptoms and the best treatment for this syndrome are not known.
