BACKGROUND: Sigmoid volvulus (SV) is a common cause of large bowel obstruction worldwide. Presenting symptoms can be nonspecific and varied amongst the elderly population, making medical and surgical management challenging. This population is at markedly increase risk of complications and mortality with surgery under general anesthesia. In this case series, we describe 4 cases of sigmoid volvulus in octogenarians. GOALS: To demonstrate that sigmoid colectomy under local anesthesia, with or without intravenous conscious sedation, is feasible and can be done safely and with a low rate of converting to a general anesthetic...

REVIEW
Xuezheng Zhang, Mahmoud Attia Mohamed Kassem, Ying Zhou, Muhammad Shabsigh, Quanguang Wang, Xuzhong Xu
Obstructive sleep apnea (OSA) is one of the important risk factors contributing to postoperative airway complications. OSA alters the respiratory physiology and increases the sensitivity of muscle tone of the upper airway after surgery to residual anesthetic medication. In addition, the prevalence of OSA was reported to be much higher among surgical patients than the general population. Therefore, appropriate monitoring to detect early respiratory impairment in postoperative extubated patients with possible OSA is challenging...

BACKGROUND: The physiologic information contained in the video photoplethysmogram is well documented. However, extracting this information during challenging conditions requires new analysis techniques to capture and process the video image streams to extract clinically useful physiologic parameters. We hypothesized that heart rate, respiratory rate, and oxygen saturation trending can be evaluated accurately from video information during acute hypoxia. METHOD: Video footage was acquired from multiple desaturation episodes during a porcine model of acute hypoxia using a standard visible light camera...

The Silver-Russell syndrome (SRS) is a rare imprinting disease associated with pre- and postnatal growth retardation, craniofacial features, and asymmetry. Genitourinary abnormalities are seen in up to 20% of affected individuals. Apart from structural renal anomalies, cryptorchidism and hypospadias occur frequently in boys, while girls often have anomalies similar to those in Mayer-Rokitansky-Küster-Hauser syndrome with congenital hypoplasia or aplasia of the uterus and upper part of the vagina. Frequently hypospadias repair and orchiopexy are difficult because of lack of buccal mucosa due to facial dysmorphism and intraabdominal position of the testicles, respectively...

Respiratory monitoring is often required in experimental physiological and pharmacological studies in rodents. Currently, the mostly used techniques are direct measurement of airflow on intubated animals and whole body plethysmography. Although the reliability of these methods has been broadly demonstrated, they also have several drawbacks such as invasiveness, high cost of use or confinement of the animals. Respiratory Inductive Plethysmography (RIP) is a non-invasive technique already used in medium-sized mammals that has not yet been evaluated in small rodents...

Schwannomas arising from cervical vagus nerve is an extremely rare benign neoplasm. The majority of patients present with insidiously growing lateral neck mass without neurological deficit. We report a case of symptomatic cervical vagal nerve schwannoma in a 32-year-old female. Complete surgical resection is the treatment of choice. However, anesthetic management of these tumors can be challenging. We describe here the complications experienced during the management of the patient.

Melanotic neuroectodermal tumor of infancy is a relatively uncommon osteolytic-pigmented neoplasm that primarily affects the jaws of infants. We report a 5-month-old male child who presented with a swelling in the right upper tooth region of upper jaw in which we face difficult mask ventilation as well as difficult intubation. Wide surgical excision was performed under general anesthesia. The uneventful course of anesthesia in the presented case was due to the thorough systemic evaluation and careful anesthetic strategy...

Nasogastric tube (NGT) placement in anesthetized and intubated is sometimes very challenging with more than 50% failure rate in the first attempt. We describe a newer innovative Sahu's three in one, technique with use of GlideScope and forward placement of intubated trachea by external laryngeal maneuver, these both techniques lead to separation of trachea from esophagus so that endoscopic jejunal feeding tube guide wire strengthen NGT can be guided and manipulated to esophagus under direct vision. After informed consent, we used Sahu's three in one combo technique to insert NGT in adult anesthetized and intubated patients of both the sexes with high success in the first attempt...

Preclinical imaging of brain activity requires the use of anesthesia. In this study, we have compared the effects of two widely used anesthetics, inhaled isoflurane and ketamine/xylazine cocktail, on cerebral blood flow and metabolism in a rat model of Parkinson's disease and l-DOPA-induced dyskinesia. Specific tracers were used to estimate regional cerebral blood flow (rCBF - [(14)C]-iodoantipyrine) and regional cerebral metabolic rate (rCMR - [(14)C]-2-deoxyglucose) with a highly sensitive autoradiographic method...

An OMS office is a complex environment. Within such an environment, a diverse scope of complex surgical procedures is performed with different levels of anesthesia, ranging from local anesthesia to general anesthesia, on patients with varying comorbidities. Optimal patient outcomes require a functional surgical and anesthetic team, who are familiar with both standard operational principles and emergency recognition and management. Offices with high volume and time pressure add further stress and potential risk to the office environment...

BACKGROUND AND OBJECTIVES: The conscious patient cooperation during neurological procedures has become necessary for the delimitation of areas to be managed by a neurosurgeon, with better results in the treatment of tumor lesions, vascular or epileptic foci, and sequelae minimization. The need for perioperative awareness (responsiveness to commands) challenges anesthesiologists to further ensure patient safety during the procedure. Several techniques have been described for this purpose...

Postconditioning with inhalational anesthetics can reduce ischemia-reperfusion brain injury, although the cellular mechanisms for this effect have not been determined. The current study was designed to test if TASK channels contribute to their neuroprotective actions. Whole cell recordings were used to examine effects of volatile anesthetic on TASK currents in cortical neurons and to verify loss of anesthetic-activated TASK currents from TASK(-/-) mice. A transient middle cerebral artery occlusion (tMCAO) model was used to establish brain ischemia-reperfusion injury...

Dual-mode multielectrode recordings have become routine in rodent neuroscience research. However, robust and reliable application of acute, multielectrode recording methods in brain especially for in vivo research remains a challenge. In patients with Parkinson's disease (PD), the efficacy of L-dopa therapy depends on its ability to restore Dopamine (DA) neurotransmission in the striatum. In this paper, We describe a low cost thin film 16 sites implantable microelectrode array (MEA) chip fabricated by standard lithography technology for in vivo test...

Hypoxic ischemic encephalopathy (HIE) is a severe consequence of cardiac arrest (CA) representing a substantial diagnostic challenge. We have recently designed a novel method for the assessment of HIE after CA. The method is based on estimating the severity of the brain injury by analyzing changes in the electroencephalogram (EEG) slow wave activity while the patient is exposed to an anesthetic drug propofol in a controlled manner. In this paper, Hilbert-Huang Transform (HHT) was used to analyze EEG slow wave activity during anesthesia in ten post-CA patients...

General anesthetics have revolutionized medicine by facilitating invasive procedures, and have thus become essential drugs. However, detailed understanding of their molecular mechanisms remains elusive. A mechanism proposed over a century ago involving unspecified interactions with the lipid bilayer known as the unitary lipid-based hypothesis of anesthetic action, has been challenged by evidence for direct anesthetic interactions with a range of proteins, including transmembrane ion channels. Anesthetic concentrations in the membrane are high (10-100 mM), however, and there is no experimental evidence ruling out a role for the lipid bilayer in their ion channel effects...

Anesthetic management of patients with dilated cardiomyopathy (DCM) is a challenge to the anesthesiologist, due to poor left systolic function, ventricular enlargement, risk of malignant arrhythmias and sudden cardiac death. Therefore, preoperative assessment and appropriate anesthetic management are important in patients with DCM. This review describes the preoperative evaluation and anesthesia considerations of patients with DCM undergoing non-cardiac surgery. Patient pathophysiology and clinical status, such as ventricular function, degree of myocardial fibrosis, resting heart rate and high-sensitivity C-reactive protein can affect survival rates...

One of the most complex tasks performed by sensory systems is "scene analysis": the interpretation of complex signals as behaviorally relevant objects. The study of this problem, universal to species and sensory modalities, is particularly challenging in audition, where sounds from various sources and localizations, degraded by propagation through the environment, sum to form a single acoustical signal. Here we investigated in a songbird model, the zebra finch, the neural substrate for ranging and identifying a single source...
