Integrated pre-surgical diagnostic algorithm to define extent of disease in cervical cancer

2020

ObjectivesSurvival of patients with cervical cancer is strongly associated with the local extent of the primary disease. The aim of the study was to develop an integrated diagnostic algorithm, including ultrasonography (USG), magnetic resonance imaging (MRI), and examination under anesthesia, to define the local extent of disease in patients with newly diagnosed cervical cancer.MethodsPatients with biopsy proven cervical cancer who underwent primary surgery from January 2013 to December 2018 in four participating centers were recruited. Patients who underwent USG, MRI, and examination under anesthesia prior to surgery were included in the study. Those for whom complete data were not availab…

Cocaine or phenylephrine/lignocaine for nasal fibreoptic intubation?

1996

In order to assess if a mixture of phenylephrine/lignocaine is as effective as cocaine for local analgesia and vasoconstriction during nasal fibreoptic intubation, 99 patients receiving topical nasal analgesia either with cocaine 10% or a mixture of phenylephrine 1% and lignocaine 4% were studied in a randomized double-blind investigation. After topical analgesia a flexible fibreoptic endoscope was advanced through a nostril. Larynx, glottis and trachea were endoscopically sprayed with lignocaine. Following induction of anaesthesia a nasotracheal tube was inserted fibreoptically. Pain intensity and amount of epistaxis during endoscopy were assessed. Blood pressure, heart rate and ECG-ST seg…

Efficacy of epidural anesthesia for retroperitoneoscopic renal biopsy

2000

Laparoscopic procedures are performed using general anesthesia due to the perceived limitations of regional anesthesia in the upper abdomen and retroperitoneum. We present our initial experience with epidural anesthesia for retroperitoneal laparoscopic renal biopsy.

Complicaciones tras técnicas de anestesia regional

2008

In recent years, there has been a considerable increase in the number of procedures carried out under regional anesthesia. The techniques used can be associated with a number of complications, which should be understood so that they can be recognized and managed appropriately. The overall incidence of reported complications associated with these techniques is low and therefore, with currently available data, we can only have an approximate idea of their incidence. The objective of this study is to systematically describe the complications that may arise from the use of neuraxial and peripheral regional anesthesia techniques.

Regional anesthesia and chronification of acute postoperative pain

2014

Chronification of acute postoperative pain is the consequence of a number of factors; the article mentions different preemptive strategies that may put a limit to its development. Certain anesthetic and analgesic techniques have been assessed over the last years, and most articles highlight the usefulness of carrying out regional anesthesia techniques from the intraoperative period through several days into the postoperative period. Preventing the patients from suffering acute postoperative pain is one of the most appropriate tools for stopping the activation of the mechanisms involved in pain chronification. None of the regional techniques are equally valid and applicable to all surgical p…

The AVL-mode: a safe closed loop algorithm for ventilation during total intravenous anesthesia.

1994

The Adaptive Lung Ventilation Controller (ALV-Controller) represents a new approach to closed loop control of ventilation. It is based on a pressure controlled ventilation mode. Adaptive lung ventilation signifies automatic breath by breath adaptation of breathing patterns to the lung mechanics of an individual patient. The specific goals are to minimize work of breathing, to maintain a preset alveolar ventilation and to prevent the occurrence of intrinsic PEEP. We ventilated 5 patients undergoing major abdominal procedures using ALV. ALV was tolerated well in all patients. Alveolar ventilation was preset between 5500 and 6500 ml/min. Serial dead space (Vds) and respiratory time constant (r…

Vitrectomía enzimática por inyección intravítrea de plasmina autóloga como tratamiento inicial del edema macular diabético difuso

2008

espanolObjetivo: Determinar si la inyeccion intravitrea de plasmina es efectiva en el tratamiento del edema macular diabetico difuso (EMDD). Diseno: Estudio piloto prospectivo, comparativo, de intervencion, serie de casos. Pacientes: Dieciocho pacientes con edema macular diabetico bilateral, recibieron como primera actuacion terapeutica una inyeccion intravitrea de plasmina en un ojo, sirviendo el ojo contralateral como control. Tratamiento: Inyeccion intravitrea de 0,2 ml de plasmina autologa bajo anestesia topica. La plasmina fue obtenida por un metodo simplificado. Principales medidas: Engrosamiento macular central (EMC) medido por tomografia de coherencia optica (OCT) y agudeza visual (…

Protocol for Low-level laser therapy in traumatic ulcer after troncular anesthesia: Case report in pediatric dentistry

2020

The aim of this study was to report a protocol of use for low-level laser therapy (LLLT) in traumatic ulcer in the lower lip after inferior alveolar nerve block anesthesia (IANBA). A 3-year-old patient, male, undergoing treatment of carious lesions was submitted to an indirect pulp capping in tooth 74 under IANBA. The procedure was completed without intercurrences, but on next day, the child presented extensive traumatic ulcer in the left lower lip, with complaint of pain. Two sequential applications with LLLT were applied in punctual mode under pressure around the lesion. After 1 week, the mother reported significant improvement. After 30 days, the lesion was fully healed. In conclusion, L…

Clonidine increases membrane-associated phospholipase A2

2005

Background and objective: An anti-inflammatory effect of α 2 -adrenoreceptor agonists has been suggested. Phospholipase A 2 is a key enzyme in the production of precursors of inflammatory lipid mediators. The aim of the present study was to investigate the effect of clonidine on phospholipase A 2 activity in an established in vitro model. Methods: Human being platelet membranes containing active phospholipase A 2 were exposed to buffer control or to three increasing concentrations of clonidine. Phospholipase A 2 was measured by a radioisotope technique. Results: A massive increase in phospholipase A 2 activity was measured after clonidine exposure leading to final values of 92.5 ′ 3.1 pmol …
