Maternal and fetal safety of fuid-restrictive general anesthesia for endoscopic fetal surgery in monochorionic twin gestations. As the risks involved are serious in nature and the procedures are carried out away from the operation room, the work area must be adequately planned with a fully equipped anesthesia work station, standard monitoring and trained personnel. Magnetic felds are always present in the scanner room whether the patient is being scanned or not. Both providers and patients must remove all ferrous (iron-containing) objects before entering the scanner room as these objects become projectiles that can damage equipment or cause injury. By minimizing the iron content, devices can be safely brought into the scanner room. T e safe proximity to the magnet can vary from device to device and few can be located directly adjacent to the scanner. Mild reactions to iodinated contrast media include perception of warmth, headache, nausea, pruritic rashes, mild urticaria but these may progress to serious reactions like vomiting, fainting, rigors, severe urticaria, chest pain, dyspnea, arrhythmias, bronchospasm and renal failure. Patients may require immediate treatment with oxygen, bronchodilators, corticosteroids, epinephrine, anti- histaminics and ventilatory support if there is glottic edema, pulmonary edema, bronchospam, severe arrhythmias, unconsciousness and cardiac arrest. Intravenous tubing and fuids should also be assured on the crash carts (pediatric and adult). Propofol, midazolam, ketamine, fentanyl, muscle relaxants, dexmedetomidine and all emergency drugs including adrenaline should also be available. Anesthesia ventilators that provide both controlled and supported modes of ventilation aford the most fexibility in patient care. Monitoring parameters such as gas concentrations, airway pressures, and tidal volume, are typically not available in the control room. T e anesthesia provider should position the machine so that the displayed parameters are visible through the control room window. A full vaporizer and low fresh gas fows will help to prevent light anesthesia and awareness, especially if an anesthetic agent analyzer is not available. T e best of these devices have a monitoring station which is located in the scanner room connected to the patient, but communicates wirelessly with a central display in the control room. T ese central displays not only allow for the patient to be monitored from outside of the scanner room, but can also be connected to an electronic recordkeeping system. Wireless devices do not require the installation costs of running wires between the scanner room and the control room, but are more expensive than their wired counterparts. Some scanner facilities have a specially constructed port between the control room and the scanner. Standard infusion pumps can be used with long lengths of tubing that travel from the pump, through the port, and to the patient’s intravenous line. Noninvasive blood pressure monitor is relatively easily monitored by changing ferrous connections to nylon. To measure invasive blood pressure, the length of pressure monitoring line should be kept to minimum to reduce damping. Use of long sampling lines complicates capnography as the time delay of the displayed waveform will increase (up to 20 seconds).

Person- Photomicrograph of a Giardia intestinalis cyst to-person transmission is the most common seen using a trichrome stain. Trophozoites multiply by longitudinal binary fssion, remaining in the lumen of the proximal small bowel, where they can be free or attached to the mucosa by a ventral sucking disk (4). Because the cysts are infectious when passed in the stool or shortly afterward, person-to-person transmission is possible. While animals are infected with Giardia, their importance as a reservoir is unclear.

Niedermeyer’s Electrocephalography: Basic Principles, Clinical Applications, and Related Fields. Sound waves travel via the external auditory canal to the tympanic mem- brane, in which they produce changes in air pressure and displacement of the tympanic membrane > displacements of the tympanic membrane are transmitted via the ossicular chain (malleus, incus, and stapes) to the oval window of the cochlea. Earphones must completely envelop the ears to reduce ambient noise; for infants and young children, tubes are placed in the auditory canal because headphones may collapse the external canals. Three types of sounds are produced: (A) Clicks: most frequently used for routine testing; produced by square wave pulse with the rising phase moving the diaphragm in one di- rection and the fall of the phase returning it to the origin; condensa- tion = initial movement of diaphragm toward eardrum, refraction = away from eardrum (refraction is used predominantly); duration approximately 100 microseconds (producing a sound complex ap- proximately 2 milliseconds in duration) (B) Pure tone: delivers exact frequency; most commonly used for pure- tone audiometry to test hearing (C) White noise: composed of all audible frequencies; delivered into non- stimulated ear to mask ambient noise and avoid bone conduction of the click to the contralateral ear iii. Each acoustic stimulus can be broken down to three components: (A) Frequency (Hertz): relates to the location of physical stimulation along the basilar membrane of the cochlea and along the tonotopic representation of the central auditory pathways (B) Intensity (decibel): refers to the loudness of the stimulus (C) Time: includes duration, rise–fall time, repetition rate, and phase of onset of the stimulus; the phase of onset refers to the initial direction of the basilar membrane displacement. Recording electrodes should be placed over vertex and bilateral ears and/ or bilateral mastoids. Refraction clicks are recommended because patients with high-frequency hearing loss may have cancellation of out-of-phase responses by conden- sation and refraction. Age is another negative variable (cont’d) (C) Latencies also increase as age increases, but the I–V interval usually remains the same; most of the changes are likely related to wave I as a result of associated cochlear dysfunction. Gender: females with shorter latencies (presumably attributable to body and brain size) c. Important interpeak intervals may occur in metabolic derangements: vitamin B12deficiency, meningitis, epilepsy, alcoholism, diabetes mellitus; diabetes mellitus and meningitis have findings consistent with damage to acoustic nerve. N400 is a potential obtained to linguistic stimuli when there is semantic incongruity. Unilateral stimulation of a motor/sensory nerve trunk sufficient to produce a moderate motor response is required. Duration: stimulus artifact is reduced by shorter duration (approximately 100 microseconds); no more than 500 microseconds. Near field: cortically generated N20 is a near-field response with maximum voltage between the contralateral central and parietal electrodes on the scalp. Far field: in contrast, far-field component is generated by subcortical structures that reach the scalp relatively rapidly via conduction by fluid (e. Criteria for impairment are decreases of 40% or more in amplitude of N13 or Erb’s point potential responses. If the N13 were absent or reduced to a greater extent than Erb’s point potential, then the lesion is more likely preganglionic. Responses to femoral stimulation are approximately 20 milliseconds earlier, and popliteal are approximately 10 milliseconds earlier (than ankle stimu- lation); thus, the tibial P37 is similar to the common peroneal P27 and the femoral P17. The tibial nerve supplies the gastrocnemius and soleus muscles of the leg, as well as the small intrinsic muscles of the foot. The proximal stimulus electrode (cathode) is placed at the ankle between the medial malleolus and the Achilles’ tendon, and the anode is placed 3 cm distal to the cathode. N34 (A) Subcortically generated far-field potential (B) Distribution is broad and can be recorded from several scalp elec- trode sites. P37 (A) Represents primary somatosensory cortex (B) Paradoxical lateralization: P37 is maximal at midline and centropari- etal scalp ipsilateral to the stimulated leg. The opening in the iris diaphragm, the pupil, determines the amount of light reaching photoreceptors. Retina has five layers: outer nuclear layer (contains cell bodies of the photore- ceptors); outer synaptic layer (aka outer plexiform layer); inner nuclear layer (contains cell bodies of horizontal, amacrine, and bipolar neurons and the cell bodies of the glial cells of Muller); inner synaptic layer; ganglion cell layer iv. Visual pigment (A) Rhodopsin: visual pigment for the rods (B) Iodopsin: visual pigment for the cones v. Three subtypes of cones that are sensitive to a particular wavelength of blue, red, or green vi. Optic nerve: approximately 50 mm long and comprises nerve fibers origi- nating in the ganglion cells; optic nerve fibers are small, myelinated fibers (92% are < 2 µm in diameter). It has been determined that full-field stimulation with patterned stimuli is best suited to evaluate anterior pathway function.
