The side effects of spinal anesthesia have been the focus of many researchers. These complications can affect patients’ satisfaction following surgery and duration of hospitalization. Therefore, factors that lead to increased risk of side effects must be identified, one of these factors is gender. This study evaluated the relationship between gender and adverse effects after spinal anesthesia.
Preeclampsia is clinically defined by hypertension and proteinuria, with or without pathologic edema that occurs after 20 weeks’ gestation, but can also present up to 4-6 weeks post-partum. Worldwide, incidence of preeclampsia is 5-14 percent of all pregnancies, while severe preeclampsia can develop to about 25 percent of all cases of preeclampsia.
Methamphetamine is one of the most commonly abused illegal stimulants and causes the release of dopamine, norepinephrine and serotonin. These neurotransmitters trigger vasospasm, causing persistent tachycardia, hypertension, and direct myocardial toxicity. Moderate usage of methamphetamine can increase cardiac output and myocardial contractility. However, larger doses can cause depression of the myocardium.
Methadone, a long-acting opioid agonist, binds to and occupies mu-opioid receptors, preventing withdrawal symptoms for 24 hours or longer, reduces craving for opioids, and, by maintaining high levels of opioid tolerance, reduces the euphoric effects of subsequent illicit opioid use. As a controlled substance with potential for abuse, methadone use is regulated in the US and other countries.
We report a case of a teenager with scoliosis and pectus excavatum who developed intraoperative refractory hypotension associated with prone position during posterior surgical correction of scoliosis. In this case, it was more difficult for the anesthetists to figure out the reason leading to severe hypotension when a surgery was partially completed, because there might be many confounding factors during surgery. Furthermore, TEE was difficult to be considered to be first diagnosis choice when patient have already underwent posterior spinal fusion surgery, compared to the cases previous reported that the surgery still did not begin.
Urinary tract infection (UTI) is the most common serious bacterial infection in febrile children younger than 3 months, with reported rates ranging from 5% to 20% depending on different series. Neonates and infants up to age 2 months who have pyelonephritis usually do not have symptoms localized to the urinary tract.
