Durante las cirugías de prótesis de cadera y especialmente aquellas por fractura de cadera pueden presentar eventos embólicos. Las complicaciones dependen principalmente de la condición clínica preoperatoria, pudiendo incluso ser subclínico si el paciente es sano. Así, gracias al progreso de la tecnología, particularmente la ecocardiografía transesofágica (ETE) y transtoraxica (ETT), se ha logrado identificar precozmente dichos fenómenos embólicos, permitiendo anticipar y tratar oportunamente una eventual descompensación cardiorrespiratoria. Se realizó un reporte de 2 pacientes con fractura de cadera, que se sometieron a una cirugía de artroplastía de cadera (AC), en los cuales mediante la vigilancia de ETT, se logró visualizar estos eventos, principalmente durante la fenestración e impactación del cotilo en el acetábulo, presentando uno de estos pacientes un impacto hemodinámico que se trató precozmente. Las causas de las embolías pueden ser variadas, como la presión ejercida por el cirujano para fenestrar e introducir la prótesis o la destrucción del tejido circundante a la lesión durante el momento de la fractura, entre otros. Así, se pueden producir embolias de trombos, grasa, hueso o incluso aire que pueda entrar al torrente sanguíneo y producir eventualmente complicaciones. Con estos hallazgos, ecográficos y en algunas oportunidades clínicos, se podría demostrar lo crítico que es aquel período de la cirugía, en donde se requiere especial atención a los cambios hemodinámicos que se puedan producir, y en el que el anestesiólogo debe estar especialmente vigilante. Particularmente, en estos casos, en que las pacientes recibieron anestesia regional y se intervino en posición de decúbito lateral, se tuvo que realizar monitoreo mediante ETT y no ETE, lo cual entrego más limitantes a la hora de conseguir buena calidad de ventanas cardiacas y por lo tanto, después de visualizar las distintas ventanas se optó por utilizar la ventana subxifoidea para visualizar la vena Cava inferior y así observar los distintos eventos embólicos circulantes. En ambas pacientes se pudieron apreciar eventos embólicos, pero en sólo una paciente tuvo compromiso cardiorrespiratorio con hipotensión, aumento de la frecuencia cardiaca y desaturación. Junto con la demostración de la posibilidad de visualización de embolías con ETT, se destaca la relevancia de que existe mayor acceso a este tipo de ecografía en gran parte de los pabellones de nuestro país, a diferencia de la ETE, en la que la sonda utilizada es de más difícil acceso por parte de los anestesistas y requiere un mayor entrenamiento.

Background: Most maternal deaths occur in low-and middle-income countries, with Chad being one of the countries with the most alarming figures. There aren't many reports of anesthetic management for cesarean delivery in these countries. Aim: To report the obstetrical anesthetic experience in a hospital in Chad, Africa in the context of an international cooperation project to reduce the global shortage of anesthesiologists. Material and Methods: Case series of pregnant woman who were admitted to the ward of the Good Samaritan University Hospital Complex. Results: Thirty-two cesarean sections were performed, all using spinal anesthesia. The median age was 22 years, seven of them being adolescents. In two cases sedation with ketamine was used due to insufficient level and in one case general anesthesia with halothane was converted due to total spinal diagnosis. In twelve patients the interruption was due to immediate maternal/fetal vital risk (emergency cesarean section), the main causes being fetal bradycardia and placental abruption. Three patients presented uterine inertia refractory to medical treatment and resolved with the B-Lynch technique. Two patients decided to have immediate skin-to-skin contact. Three neonates had to be resuscitated with positive pressure ventilation, one of them died. No operative deaths were reported in the patients who underwent c-section, but there was one maternal death due to severe preeclampsia and postpartum hemorrhage after vaginal delivery. No epidural analgesia was requested for labor. Conclusions: This individual report provides insight into a particular reality with very limited staff and resources.

The importance of breastfeeding with its positive impact on the wellbeing of the mother-infant pair is well established. Anesthesiologists should encourage the promotion of lactation by being willing to give reassurance during the preoperative period and preparing a plan that does not interfere with safe breastfeeding. There is concern regarding the transfer of drugs into breast milk, which may lead to inconsistent advice from many health professionals and to early discontinuation. However, evidence shows that most anesthetic drugs are safe in terms of transfer into breast milk, and hence, compatible with breastfeeding, which should be resumed after anesthesia as soon as the mother is alert and feels well enough to hold her infant, without the need to “pump and dump”. This review provides pharmacokinetic information on commonly used anesthesia drugs and their passage into breast milk, to help practitioners discuss risks and benefits with the mother, emphasizing that anesthesia should not interfere with the benefits of breastfeeding. Four practical clinical scenarios are presented: pregnant women concerned about the effect of epidural analgesia on subsequent breastfeeding, spinal anesthesia for c-section and lactation, patients who will receive general anesthesia during cesarean section, and finally women who are breastfeeding and require anesthesia for elective or urgent surgery. Neuraxial anesthesia allows for better pain control and immediate skin-to-skin contact at the time of childbirth. Also, it interferes the least with the woman’s ability to care for her infant. Regional techniques, opioid-sparing techniques and outpatient surgery are preferred. Drugs such as opioids and longer-acting benzodiazepines should be administered cautiously, particularly in repeat doses.
