Efficacy of Neuromodulation Interventions for the Treatment of Sexual Dysfunction: A Systematic Review.

OBJECTIVES: The primary aim of this review was to analyze the literature for the efficacy of neuromodulation interventions in treating both male and female sexual dysfunction. MATERIALS AND METHODS: Studies were identified from PubMed, Scopus, PsychINFO, CINAHL, and Cochrane. Results were synthesized qualitatively without pooling owing to the heterogeneous nature of outcome assessments. RESULTS: Overall findings from studies generally supported that neuromodulation interventions were associated with improvement in sexual function. Specific domains that improved in male patients included erectile function, desire, and satisfaction, whereas desire, arousal, orgasm, lubrication, quality of "sex life," intercourse capability, and dyspareunia improved in female patients. Male ejaculation, orgasm, and intercourse capability were the only domains that continued to decline after the use of neuromodulation interventions, although this was only reported in one study. CONCLUSION: Our review suggests that there may be promise and potential utility of neuromodulation in improving sexual dysfunction; however, further research is needed.

Cervical Spinal Cord Stimulation for the Treatment of Headache Disorders: A Systematic Review.

OBJECTIVES: Chronic headache remains a major cause of disability and pain worldwide. Although the literature has extensively described pharmacologic options for headache treatment and prophylaxis, there remains a paucity of data on the efficacy of neuromodulation interventions for treatment of headache unresponsive to conventional pharmacologic therapy. The primary aim of this review was to appraise the literature for the efficacy of cervical spinal cord stimulation (cSCS) in treating any intractable chronic headache, including migraine headaches (with or without aura), cluster headache, tension headache, and other types of headaches. MATERIALS AND METHODS: In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, we performed a systematic review by identifying studies in PubMed, Embase (Scopus), Web of Science, and Cochrane Central Register of Controlled Trials that assessed cSCS to treat chronic headache. Data were synthesized qualitatively, with primary outcomes of headache intensity and frequency. The secondary outcome was adverse effects. RESULTS: In total, 16 studies comprising 107 patients met the inclusion criteria. Findings were presented based on type of headache, which included migraine headache with or without aura, cluster headache, trigeminal neuropathy, occipital neuralgia, posttraumatic headache, cervicogenic headache, short-lasting unilateral neuralgiform headache with autonomic symptoms, and poststroke facial pain. Per the Grading of Recommendations, Assessment, Development and Evaluations criteria, there was very low-quality evidence that cSCS is associated with a decrease in migraine headache frequency, migraine headache intensity, and trigeminal neuropathy intensity. Placement for cSCS leads ranged from C1 to C4. CONCLUSIONS: Our review suggests promising data from observational studies that cSCS may be helpful in decreasing frequency and intensity of chronic intractable headache. Future well-powered, randomized controlled trials are needed.

KCNQ channels in nociceptive cold-sensing trigeminal ganglion neurons as therapeutic targets for treating orofacial cold hyperalgesia.

BACKGROUND: Hyperexcitability of nociceptive afferent fibers is an underlying mechanism of neuropathic pain and ion channels involved in neuronal excitability are potentially therapeutic targets. KCNQ channels, a subfamily of voltage-gated K(+) channels mediating M-currents, play a key role in neuronal excitability. It is unknown whether KCNQ channels are involved in the excitability of nociceptive cold-sensing trigeminal afferent fibers and if so, whether they are therapeutic targets for orofacial cold hyperalgesia, an intractable trigeminal neuropathic pain. METHODS: Patch-clamp recording technique was used to study M-currents and neuronal excitability of cold-sensing trigeminal ganglion neurons. Orofacial operant behavioral assessment was performed in animals with trigeminal neuropathic pain induced by oxaliplatin or by infraorbital nerve chronic constrictive injury. RESULTS: We showed that KCNQ channels were expressed on and mediated M-currents in rat nociceptive cold-sensing trigeminal ganglion (TG) neurons. The channels were involved in setting both resting membrane potentials and rheobase for firing action potentials in these cold-sensing TG neurons. Inhibition of KCNQ channels by linopirdine significantly decreased resting membrane potentials and the rheobase of these TG neurons. Linopirdine directly induced orofacial cold hyperalgesia when the KCNQ inhibitor was subcutaneously injected into rat orofacial regions. On the other hand, retigabine, a KCNQ channel potentiator, suppressed the excitability of nociceptive cold-sensing TG neurons. We further determined whether KCNQ channel could be a therapeutic target for orofacial cold hyperalgesia. Orofacial cold hyperalgesia was induced in rats either by the administration of oxaliplatin or by infraorbital nerve chronic constrictive injury. Using the orofacial operant test, we showed that retigabine dose-dependently alleviated orofacial cold hyperalgesia in both animal models. CONCLUSION: Taken together, these findings indicate that KCNQ channel plays a significant role in controlling cold sensitivity and is a therapeutic target for alleviating trigeminal neuropathic pain that manifests orofacial cold hyperalgesia.

Chronic Abdominal Discomfort Syndrome (CADS): Defining and Discussing a Novel Diagnosis.

In this article, we propose a new diagnostic paradigm known as Chronic Abdominal Discomfort Syndrome (CADS). Patient's presentation centers around chronic abdominal pain not explained by acute pathology with or without accompanying dyspepsia, bloating, nausea and vomiting among other symptoms. The pathophysiology is noted to be neurogenic, possibly stemming from visceral sympathetic nerves or abdominal wall afferent nerves. Diagnosis is supported by signs or symptoms traversing clinical, diagnostic and functional criteria. Included is a tool which can assist clinicians in diagnosing patients with CADS per those domains. We hope to facilitate primary care physicians' and gastroenterologists' utilization of our criteria to provide guidance for selecting which patients may benefit from further interventions or evaluation by a pain physician. The pain physician may then offer interventions to provide the patient with relief.

Ultrasound-guided transversus abdominis plane catheter for chronic abdominal pain.

BACKGROUND AND OBJECTIVES: Neural blockade of the thoracolumbar nerves supplying the anterior abdominal wall through transversus abdominis plane (TAP) has been investigated for different applications mainly for the acute pain management following abdominal surgical procedures. The role of this block for chronic pain syndromes is still to be discovered, and its value in chronic abdominal pain needs to be studied. We are presenting new application of the TAP technique for management of chronic abdominal pain syndrome using the continuous infusion. CASE REPORT: We present a case of an 18-year-old girl who underwent an uneventful laparoscopic cholecystectomy. Postoperatively, patient complained of chronic pain at the site of the surgery. All diagnostic and imaging studies were negative for a surgical or a medical cause. Multiple interventions including epidural blocks, transcutaneous electrical neural stimulation, and celiac plexus blocks had failed to relieve the pain. After discussion with the patient about the diagnostic nature of the procedure and the likelihood of recurrence of pain, TAP block was performed on the right side with significant improvement of pain for about 24 hours. The degree of pain relief experienced by the patient was very dramatic, which encouraged us to proceed with an indwelling TAP catheter to allow for continuous infusion of a local anesthetic. The patient was sent home with the continuous infusion through a TAP catheter for 2 weeks. From the day of catheter insertion and up to 9 months of follow-up, patient had marked improvement of her pain level as well as her functional status and ability to perform her daily activities, after which our acute pain team stopped following the patient. CONCLUSION: A successful TAP block confirmed the peripheral (somatic) source of the abdominal pain and provided temporary analgesia after which an indwelling catheter was inserted, which provided prolonged pain relief.

Painful Diabetic Peripheral Neuropathy - A Survey of Patient Experiences.

Purpose: An online survey was conducted in the USA to obtain information about the knowledge and experiences of patients with painful diabetic peripheral neuropathy (pDPN). Patients and Methods: 506 adults with diabetes and pDPN affecting the feet for ≥6 months, for which pain medication had been prescribed for ≥6 months, completed an online survey questionnaire in March 2021. Results: 79% of respondents had type 2 diabetes, 60% were male, 82% were Caucasian and 87% had comorbidities. Pain was significant to severe in 49% of respondents, and 66% had disability due to nerve pain. Anticonvulsants, over-the-counter pills and supplements were the most commonly used medications. Topical creams/patches were prescribed in 23% of respondents. 70% had tried multiple medications for their pain. 61% of respondents had to see ≥2 doctors before receiving a correct diagnosis of pDPN. 85% of respondents felt that the doctor understood their pain and its impact on their life. 70% had no difficulty finding the information they wanted. 34% felt insufficiently informed about their condition. A medical professional was the primary, and most trusted, source of information. Frustration, worry, anxiety and uncertainty were the most commonly reported emotions. Respondents were generally eager to find new medications for pain relief and desperate for a cure. Lifestyle changes because of nerve pain were most commonly associated with physical disabilities and sleep disturbance. Better treatments and freedom from pain were the overriding perspectives when considering the future. Conclusion: Patients with pDPN are generally well informed about their pain and trust their doctor but remain unsatisfied with their current treatment and struggle to find a lasting solution for their pain. Early identification and diagnosis of pain in diabetics, and education about treatments, is important to minimize the impact of pain on quality of life and emotional well-being.

A propensity-matched comparison of the incidence of new-onset postoperative atrial arrhythmias in cardiac and noncardiac thoracic surgery patients.

OBJECTIVE: The primary aim of this investigation was to compare the incidence of new-onset postoperative atrial arrhythmias (POAAs) in cardiac versus noncardiac thoracic surgery patients. A subgroup analysis also was performed in the cardiac surgery patients comparing POAAs in patients who underwent cardiac surgery on and off cardiopulmonary bypass (CPB). DESIGN: This was a retrospective study using the Department of Cardiothoracic Anesthesia patient registry. All patients (n = 33,500) undergoing cardiac (n = 29,057) and noncardiac thoracic (n = 4,443) surgeries between 1993 and 2004 were identified from the patient registry. Two propensity-matched comparisons for the incidence of POAAs were made: (1) in cardiac surgery patients versus noncardiac thoracic surgery patients and (2) in patients undergoing cardiac surgery with versus without CPB. SETTING: A large metropolitan multidisciplinary clinic. PARTICIPANTS: Patients. INTERVENTION: No interventions were done because this was a retrospective study. MEASUREMENTS AND MAIN RESULTS: The cardiac patients had a significantly higher incidence of POAAs when compared with noncardiac thoracic surgery patients (11.6% v 7.5%, p < 0.001). There was no significant difference in the incidence of POAAs between patients undergoing CPB versus off-pump CPB (13.3% v 12.3%, p = 0.3). CONCLUSION: The incidence of new-onset POAAs was higher in patients undergoing cardiac surgery than in patients undergoing noncardiac thoracic surgery in propensity-matched patient groups. CPB was not associated with new-onset POAAs.

Patient reported and anatomical outcomes after surgery for pelvic organ prolapse.

AIM: Primary aim was to modify Pelvic Floor Distress Inventory (PFDI) and Pelvic Floor Impact Questionnaire (PFIQ) to assess pelvic organ prolapse (POP) in Arabic Muslim women. Secondary aim was to compare functional and anatomical outcomes of POP repair. METHODS: Questionnaire. A characteristic (prayer) was added to PFIQ. Linguistic validation of questionnaires was then done. Twenty cases were enrolled in a pilot study to test internal consistency and reliability. Subsequent study. Prospective study included women with symptomatic POP >or= stage II. History, examination by POP-Q, and administration of PFDI and PFIQ, were done before and 6 months after surgery. RESULTS: Questionnaire. Internal consistency of added question was good (Cronbach alpha = 0.78). Test-retest reliability of individual PFIQ items was variable. Subsequent Study. Between September 2004 and February 2007, 78 consecutive women were included. Cystocele, rectocele, and no site predominated in 74.4%, 17.9% and 7.7% of cases, respectively. Preoperatively 19.2%, 15.4% and 47.4% reported stress, urge, and mixed incontinence, respectively. Overall and individual urinary symptoms scores improved significantly after surgery. There were significant improvements in individual symptoms of constipation, splint to defecate and losing not well formed stools. Low self-esteem was most negative impact of prolapse on quality of life (QoL) followed by prayer. After surgery 90% of subjects had anatomical cure. After surgery, QoL issues are significantly related to anatomic location of prolapse as determined by POP-Q. CONCLUSIONS: Modified PFIQ and PFDI are suitable to assess POP among Muslim women. Postoperatively, many prolapse-related symptoms and QoL significantly improve after surgery on the short term with an anatomic cure rate of 90%.

"Like a Normal Person Again": A Qualitative Analysis of the Impact of Headache Surgery.

BACKGROUND: Outcomes after migraine surgery have been previously assessed using quantitative measurements, including the migraine headache index. Qualitative methodologies offer the ability to analyze patients' perceptions and pain experience, and may point to changes in domains not captured by quantitative instruments. The purpose of this study was to characterize individual patients' experiences with migraines and to analyze how patients' experience of headaches changes in relation to surgery. METHODS: Patients who previously underwent migraine surgery performed by a single surgeon participated in semistructured interviews at least 1 year after surgery. Purposive sampling was used to recruit patients [n = 15 (73 percent female)]. Interviews were transcribed verbatim. A multidisciplinary team with backgrounds in surgery, pain management, medicine, and health services research coded and analyzed transcripts. RESULTS: Participants reported improvements in one or more domains of pain following surgery, and changes in medication use and effectiveness. Even in individuals with persistent pain postoperatively, surgery appeared to facilitate an improvement in headache self-efficacy, including an ability to participate in daily activities. Migraineurs frequently described a new degree of control over at least one aspect of their pain. CONCLUSIONS: Migraine surgery appears to positively impact patients' lives in ways that support and expand on previously published outcomes. Patients report benefiting from surgery in ways that are not currently captured in commonly used metrics. This study's findings support the need for more specific patient-reported outcome measures to help clinicians and patients understand the impact of surgery and which outcomes matter most to patients.

Muscle invasive bladder cancer in Upper Egypt: the shift in risk factors and tumor characteristics.

BACKGROUND: In Egypt, where bilharziasis is endemic, bladder cancer is the commonest cancer in males and the 2nd in females; squamous cell carcinoma (SCC) is the commonest type found, with a peculiar mode of presentation. The aim of this study is to identify and rank the risk factors of muscle invasive bladder cancer (MIBC) in Upper Egypt and describe its specific criteria of presentation and histopathology. METHODS: This is an analytical, hospital based, case controlled study conducted in south Egypt cancer institute through comparing MIBC cases (n = 130) with age, sex and residence matched controls (n = 260) for the presence of risk factors of MIBC. Data was collected by personal interview using a well designed questionnaire. Patients' records were reviewed for histopathology and Radiologic findings. RESULTS: The risk factors of MIBC were positive family history [Adjusted odds ratio (AOR) = 7.7], exposure to pesticides [AOR = 6.2], bladder stones [AOR = 5], consanguinity [AOR = 3.9], recurrent cystitis [AOR = 3.1], bilharziasis [odds ratio (OR) = 5.8] and smoking [OR = 5.3]. SCC represented 67.6% of cases with burning micturition being the presenting symptom in 73.8%. CONCLUSION: MIBC in Upper Egypt is usually of the SCC type (although its percentage is decreasing), occurs at a younger age and presents with burning micturition rather than hematuria. Unlike the common belief, positive family history, parents' consanguinity, exposure to pesticides and chronic cystitis seem to play now more important roles than bilharziasis and smoking in the development of this disease in this area.

An Intervention to Improve Medical Student Perception of Observation and Feedback During an Anesthesiology Clerkship.

BACKGROUND: Between 2011 and 2013, medical students at a large, tertiary academic hospital reported a lower-than-expected perception of direct observation and feedback during their third- and fourth-year clinical clerkships. The anesthesiology clerkship is a team-based care model that involves an anesthesiologist, resident or anesthetist, and student. This model allows for direct supervision of all patient interactions and procedures. Despite this structure, medical students reported an acceptable but lower-than-anticipated perception of direct observation and feedback taking place during a 2-week anesthesiology clerkship. METHODS: Interventions were proposed to improve student awareness of the supervision, teaching, and feedback taking place. A skills checklist for intravenous (IV) line placement that an anesthesia provider completed while observing the student was chosen as a meaningful intervention to improve the students' perception of observation and feedback. This checklist required direct observation of the IV line placement clinical skill, and the evaluator was directed to give oral feedback to the student. Students were surveyed regarding their perceptions of direct observation and feedback during a 4-year period, 2 years prior to and 2 years after implementation of the IV checklist. RESULTS: No statistically significant difference was noted between the preintervention and postintervention groups. CONCLUSION: While formal observation of and feedback on an IV placement did not change student perception, the intervention showed that a more in-depth analysis of the "educational alliance" desired during an anesthesiology clerkship is warranted, especially as medical education continues to evolve.

The association between preinduction arterial blood pressure and postoperative cardiovascular, renal, and neurologic morbidity, and in-hospital mortality in elective noncardiac surgery: an observational study.

BACKGROUND: The association between preinduction blood pressure (BP) and postoperative outcomes after noncardiac surgery is poorly understood. Whether this association depends on the presence of risk factors for poor cardiovascular outcomes remains unclear. Accordingly, we evaluated the association between preinduction BP and its different components; isolated systolic hypertension (ISH) and wide pulse pressure (WPP), and postoperative complications in patients with and without revised cardiac risk index (RCRI) components. METHODS: We analysed consecutive patients undergoing elective noncardiac surgery at Cleveland Clinic. Separate analyses were undertaken for patients with and without any RCRI components. Preinduction BP was assessed both continuously and according to hypertension stages. Logistic regression was used to assess the association between the BP values and composite of in-hospital mortality as well as cardiovascular, renal, and neurologic morbidity. We considered the following potential confounding factors in our analysis; year of surgery, age, sex, race, BMI, and American College of Cardiology/American Heart Association surgical procedure risk classification. RESULTS: Of 58 276 patients, 10 512 had one or more RCRI components. For those with no RCRI, no significant relationship was found between preinduction BP and outcome after adjustment for confounders. For patients with RCRI, the adjusted incidence was the greatest among those with normal preinduction SBP and DBP of less than 70 mmHg. Among patients with preinduction DBP greater than 75 mmHg, risk rose slightly with increasing SBP. However, we found no association between preinduction hypertension stages, ISH, or WPP and the composite outcome in patients with and without RCRI. CONCLUSION: Preinduction low DBP less than 70 mmHg or SBP greater than 160 mmHg and not ISH, nor WPP were associated with an increased risk of postoperative complications in noncardiac surgery patients with one or more RCRI components.

Echocardiographic assessment of mitral valve morphology after Percutaneous Transvenous Mitral Commissurotomy (PTMC).

AIMS: PTMC produces significant changes in mitral valve morphology as improvement in leaflets mobility. The determinants of such improvement have not been assessed before. METHODS AND RESULTS: The study included 291 symptomatic patients with mitral stenosis undergoing PTMC. Post-PTMC subvalvular splitting area was a determinant of post-PTMC excursion in both the anterior (B 0.16, 95% CI 0.03 to 0.30, p < 0.05) and the posterior (B 0.12, 95% CI 0.01 to 0.24, p < 0.05) leaflets. Another determinant was the post-PTMC transmitral pressure gradient for anterior (B -0.02, 95% CI -0.04 to -0.005, p < 0.01) and posterior (B -0.01, 95% CI -0.04 to -0.005, p < 0.05) leaflets excursion. The relationship between post-PTMC MVA and leaflet excursion was non-linear "S curve". There was a steep increase of both anterior (p, 0.02) and posterior (p, 0.03) leaflets excursion with increased MVA till the MVA reached a value of about 1.5 cm2; after which both linear and S curves became nearly parallel. CONCLUSION: The improvement in leaflets excursion after PTMC is determined by several morphologic and hemodynamic changes produced in the valve. The increase in MVA improves mobility within limit; after which any further increase in MVA is not associated by a significant improvement in mobility in both leaflets.

Effective Management of Trigeminal Neuralgia by Neurostimulation.

BACKGROUND: Treatment of trigeminal neuralgia can be challenging for many physicians; patients who do not respond to conventional treatments and traditional surgical approaches often continue to suffer with pain. The peripheral nerve stimulator (PNS) has been used to treat many chronic pain conditions, but few reports exist about its use to treat trigeminal neuralgia. CASE REPORT: We present the case of a patient with trigeminal neuralgia resistant to conventional techniques of pain management. Conservative pain management was attempted but was ineffective. As a result, a PNS was placed with minimally invasive surgery. Pain scores were recorded before and after the procedure, and the patient reported complete resolution of her pain. CONCLUSION: PNS implantation can be a safe and effective method to treat trigeminal neuralgia. More research is needed to define its mechanism of action.

Management challenges in the passing-through technique using a fogarty catheter to remove an endobronchial foreign body from an infant.

BACKGROUND: Foreign body aspiration (FBA) is a potentially life-threatening condition in children, and removal of an aspirated bead can be difficult. CASE REPORT: An 11-month-old male infant presented with a history of choking 6 days prior to admission. FBA was suspected, and initial examination revealed a bead occluding the left main bronchus. The surgeon tried to retrieve the foreign body, but the patient developed coughing episodes with desaturation. The patient was intubated and a bronchoscopy was performed with a flexible bronchoscope. A Fogarty catheter was passed through the bronchoscope and then advanced through the bead opening. The distal balloon was inflated, and the bead was removed as the Fogarty catheter was withdrawn. CONCLUSION: We successfully removed an aspirated bead from an infant using the passing-through technique with a Fogarty catheter. Maintaining spontaneous ventilation for as long as possible and good coordination between the anesthesiologist and surgeon are crucial in such cases.

A Double-Blind Randomized Controlled Trial Comparing Epidural Clonidine vs Bupivacaine for Pain Control During and After Lower Abdominal Surgery.

BACKGROUND: Alpha-2 adrenergic agonists produce safe and effective analgesia, but most investigations studying the analgesic effect of alpha-2 adrenoceptor agonists postoperatively included previous or concomitant administration of other analgesics. Because clonidine potentiates the effect of these drugs, its own intrinsic analgesic effect has been difficult to establish. This study was designed to compare the intraoperative and postoperative effects of epidural clonidine vs bupivacaine for patients undergoing lower abdominal surgery. METHODS: This randomized controlled trial included 40 patients aged 18-50 who were scheduled for elective lower abdominal surgery. Patients were randomly divided into 2 groups. Group I (n=20) received epidural clonidine; Group II (n=20) received epidural bupivacaine. Intraoperative and postoperative hemodynamics, pain scores, and complications were monitored. RESULTS: Mean pain scores were significantly lower in Group I compared to Group II (1.5 ± 0.5 compared to 3.4 ± 1.0, respectively) in the first 12 hours after surgery. Sedation was more prominent in Group I until 9 hours after surgery. Opioid requirements were significantly lower in Group I. Respiratory rate was similar in the 2 groups. Group I had larger decreases from baseline in systolic blood pressure and diastolic blood pressure than Group II. Heart rate in Group I was reduced from baseline, while it was increased in Group II. Less postoperative nausea and vomiting, urinary retention, pruritus, and shivering were observed in Group I. CONCLUSION: Compared to bupivacaine, epidural clonidine provided effective intraoperative and postoperative analgesia in selected patients, resulting in a decreased intravenous pain medication requirement and prolonged duration of analgesia after epidural infusion was discontinued.

Amputation as an Unusual Treatment for Therapy-Resistant Complex Regional Pain Syndrome, Type 1.

BACKGROUND: Complex regional pain syndrome, type 1 (CRPS-1) causes severe pain that can be resistant to multiple treatment modalities. Amputation as a form of long-term treatment for therapy-resistant CRPS-1 is controversial. CASE REPORT: We report the case of a 38-year-old man who failed all treatment modalities for CRPS-1, including medication, steroid injections, and spinal cord stimulator implantation. Below-the-knee amputation to relieve intractable foot and ankle pain resulted in a favorable outcome for this patient. CONCLUSION: Select patients with severe CRPS-1 who are unresponsive to all forms of treatment for pain may benefit from amputation as a last option for relief of suffering. Larger studies are needed to prove the efficacy of amputation.

Anesthetic management of patients with intracranial aneurysms.

BACKGROUND: Stroke is a leading cause of death and disability worldwide. Aneurysmal subarachnoid hemorrhage (aSAH), a significant cause of hemorrhagic stroke, continues to have poor prognosis. Early diagnosis and treatment are key to improving outcomes. Subarachnoid hemorrhage (SAH) and aSAH are often accompanied by multiple comorbidities, making anesthetic management of these patients complex. METHODS: This article summarizes the goals of anesthetic management of patients with cerebral aneurysm, including preoperative considerations, intraoperative management, and postoperative considerations. RESULTS: Hemodynamic monitoring is an important aspect of management. Use nicardipine, labetalol, and esmolol to avoid increases in blood pressure that may cause aneurysm rupture, and avoid low blood pressure as this may decrease cerebral perfusion pressure. Nimodipine is recommended for vasospasm prophylaxis in all patients with aSAH. The hypertension arm of Triple H therapy (hypertension, hypervolemia, hemodilution) is the most important to improve cerebral perfusion. Erythropoietin has shown some promise in lowering the incidence of vasospasm and delayed cerebral ischemia. Albumin is the preferred colloid. CONCLUSION: Anesthetic management of patients with aSAH and SAH is a complex endeavor. Careful consideration of individual patient status, optimal techniques, and the safest evidence-based methods are the best options for successfully treating these life-altering conditions.

Simultaneous antiphospholipid syndrome and heparin-induced thrombocytopenia in a single patient.

Antiphospholipid syndrome and heparin-induced thrombocytopenia are immune-mediated thrombotic conditions initiated by 2 distinct antibodies each targeting a discrete protein-antigen complex. Although produced by 2 different types of antibodies, they are similar in their autoimmune and pathophysiologic mechanisms. We present a case with simultaneous antiphospholipid syndrome and heparin-induced thrombocytopenia syndromes that sheds light on the correlation between these 2 syndromes.
