De a era publicada trimestralmente. Airways management is fundamental for anesthesiologists, especially during induction of anesthesia and after extubation, when laryngeal spasm is more common. The anesthesiologist should know pharyngeal-laryngeal physiology and the risk factors for airways obstruction, since this is a potentially severe complication with a multifactorial etiology that can develop during anesthesia and whose consequences can be catastrophic. A delay in the diagnosis or treatment and its evolution can lead to hypoxemia, acute pulmonary edema, and, eventually, death of the patient. In this context, the objective of this report was to review the measures that should be taken in cases of laryngospasm because adequate oxygenation and ventilation may be compromised in this situation.. This review article presents the mechanisms of airways management, discussing the most relevant aspects and etiology, pathophysiology, treatment, and prevention of laryngospasm.. The literature has several recommendations on the treatment or prevention of laryngospasm, but none of them is completely effective.

All patients in our study suffered a decrease in basal HR. Severe or moderate bradycardia is the most important predictor signal of cardiac arrest CA during SA.
In the series of consecutive SA reviewed in this paper, there was one case of CA, which occurred in a female ASA I patient, aged 30, who underwent liposuction. The anesthesiologist who performed the puncture and started the anesthesia had to leave the OR and left as substitute another anesthesiologist with less experience in the technique. Very severe bradycardia came next and, in sequence, asystole observed by isoelectric baseline in cardioscope and pulse oximeter. Treatment was immediate and consisted of external cardiac compression ECM made by the surgeon, ventilation under mask, followed by tracheal intubation TI and administration of intravenous adrenaline 1 mg.
The response was rapid and favorable with cardiac activity return in sinus rhythm, rate greater than bpm and BP P. Benitez et al. The patient recovered in the ICU and was later discharged without neurological sequelae. It was, therefore, an absolutely avoidable CA in which the anesthetic technique cannot be exclusively held responsible.
Some studies include young and healthy patients in CA risk groups during SA. One needs to reconsider whether acts of negligence or recklessness are not under-investigated at the conclusion of these statistics. By positioning the patients immediately supine and tilted head-down, the hyperbaric anesthetic mixture is dispersed in the cephalic direction and the initial concentration of the solution will be diluted in the course as it moves away from the puncture site.
The patient does not feel the pain of liposuction in the arms, but can still move them. The internal intercostal muscles expiratory and external inspiratory , due to the decreasing CM are less blocked as they approach T1. The Phrenic Nerve, responsible for the main muscle of inspiration activity, has its origin in the anterior roots of C2 and C3 and its motor activity is preserved for the same reasons indicated for the brachial plexus motor function.
The mismatch between the active diaphragm and other respiratory partially or totally relaxed muscles causes diaphragmatic or external paradoxical breathing. For the reasons described, as the spinal blocks reach more cephalic metameric levels, the inspiratory capacity is less changed, while the expiratory capacity is reduced in direct proportion to the number of blocked metameric levels.
For this reason, the SA with the method described in this Lumbar spinal anesthesia with cervical nociceptive blockade article should be avoided in obese patients and in those with chronic lung disease. The episodes of apnea occurred before the 30 min after the subarachnoid puncture, with progressive decrease in respiratory rate and consciousness for periods of time varying between 5 and 35 min.
Patients were ventilated manually in semi-closed system with facial mask and one of them with laryngeal mask. Spontaneous breathing and consciousness gradually returned without memory of the fact.
It is reasonable to disregard that these periods of apnea and unconsciousness were produced predominantly by critical concentrations of the anesthetic mixture in the CSF around the brainstem. All patients improved quickly with the usual maneuvers of upper airway clearance. Sedation is an issue that requires special care, as many patients say they are sleepy and did not hear or feel anything.
This dilemma requires patience and persuasion strategies by the anesthesiologist, because excessive sedation is associated with lower cardiorespiratory safety.
Patients who received oral premedication with midazolam 15 mg 15 min before being transported to the OR had less need for intravenous sedatives and more stable and secure degree of sedation with lower incidence of reduced hemoglobin saturation in the intraoperative period. During liposuction, fat grafts, and mammoplasties, the surgical team usually asks for several changes of patient positioning. The loss of sympathetic vasomotor activity can provide adaptive imbalances between intravascular continent and content during sudden movements, especially in the great vessels with repercussions on rhythm, CO, and BP.
The prone position during spinal blocks is related to several reports of serious complications. The guidelines for positioning changes see above were effective in preventing complications. Fifty six percent of patients were discharged from PACU without referring any adverse effect, with cardiovascular stability, without use of vasoactive drugs, conscious, and without pain.
A 56 year old patient complained of paresis and paresthesia in the distal end of the right leg in the sensory and motor area of L4 and L5,65 with the onset of symptoms before hospital discharge. The transient neurological symptoms were treated with common analgesics, pregabalin, and physiotherapy, and showed progressive improvement from the 15th postoperative day and subsequent complete resolution.
Headache was mild to moderate and evolved favorably with common painkillers without autologous epidural blood patch.
The technique safety depends on the absolute respect to the contraindications of SA, knowledge of the physiological effects, and attentive and constant vigilance of the anesthesiologist to the correct treatment of the potential complications of intravenous sedation associated with SA. References 1.
