Tonic pupil was observed in a 67 year-old patient following a retinal detachment repair with pars plana vitrectomy, endolaser and silicone oil tamponade performed under retrobulbar anesthesia. The probable location of disturbance is the postganglionic parasympathetic fibers in the short ciliary nerves along their course to the pupil in the suprachoroidal space. A likely explanation for this phe...

Prader-Willi syndrome (PWS) is a sporadic disorder of chromosome abnormalities with an estimated prevalence of 1 in 15,000. It mainly affects the central nervous system, and often involves the hypothalamus. Both general and regional anesthesia for these patients is difficult mainly due to morbid obesity. Other common problems include hypotonia, disturbance in thermoregulation, arrhythmia, cor p...

We report on the anesthetic experience of a 38-week pregnant patient in labor with an upper cervical spinal cord injury after an unusual trauma. She was transferred from a district hospital to our medical center with acute quadriplegia and sensory loss. Plain cervical spine x-ray and computed tomographic scan showed a C2 odontoid (dens of axis) process type II fracture and atlantoaxial (C1-C2) ...

Pseudohypoxic brain swelling (PHBS) is known to be an uncommon event that may occur during and following an uneventful brain surgery, when negative suction drainage is used. The cerebrospinal fluid loss related to suction drainage can evoke intracranial hypotension that progress to PHBS. The main presentations of PHBS are sudden unexpected circulatory collapses, such as severe bradycardia, hypo...

We report a case of large thyroid carcinoma with tracheal and esophageal invasion who presented with preoperative stridor scheduled for total thyroidectomy and segmental tracheal resection. Careful and comprehensive preoperative anesthetic planning was done. Extracorporeal circulation membrane oxygenation (ECMO) was set up and running prior to induction under local anesthesia, due to an increas...

BACKGROUND Induction of general anesthesia in a patient with compromised airway has always caused dilemma to anesthesiologist, especially for toddler this is paramounted. CASE PRESENTATION An 18 month old boy had a huge sized lingual mass which not only filled entire oral cavity but protruded outside the mouth up to about 5 cm. Having in mind the diagnosis of hemangioma, prior to induction it...

The technological complexity of implantable arrhythmia management devices, specifically pacemakers and defibrillators, has increased dramatically since their introduction only a few decades ago. Patients with such devices are encountered much more frequently in hospitals and surgery centers, yet anesthesia provider knowledge of safe and proper management is often incomplete. Anesthesia textbook...

Hernioscopy is essentially hernia sac laparoscopy. Hernia repair has evolved over the years with better outcomes; however, strangulated inguinal hernias are acute surgical emergencies which require emergent operative intervention. During anesthesia induction and/or after incision, hernia self-reduction is possible, with or without compromised bowel, back into the abdominal cavity. It is pivotal...

In this paper, we discuss the first application of recently developed L1-adaptive control methods for the closed-loop control of anesthesia delivery during surgery. Our initial objective, described herein, is to design controllers that are robust to inter-patient variability, such that patients follow a prespecified Bispectral Index (BIS) profile. The controllers are then evaluated on their abi...

The anesthetic management of centenarians is challenging, since they have loss of functional reserve in all organs. The mortality rate of 25 % is reported in patients over 100 years old who underwent emergency surgery. The transversus abdominis plane block has been shown to provide effective analgesia in laparoscopic cholecystectomy. A 101-year-old woman was diagnosed with grade I (mild) acute ...
