Spouses and family members of relatively young patients had higher rates of anxiety and depression. In contrast to the literature, depression was more common than anxiety among the relatives of ICU patients. Further research is needed on the impact of cultural and regional differences on anxiety and depression rates in family members of ICU patients.
Our results show that dexmedetomidine can easily be preferred over propofol in fast-track cardiac anesthesia due to its significant advantages of shorter extubation time and higher postoperative patient satisfaction scores.
Administration of irrigation solutions at room temperature in PCNL operations causes the body temperature to decrease significantly, which results in postoperative complications such as late emergence from anesthesia, late recovery from anesthesia, and shivering.
Contrary to the common belief, it is demonstrated in this study that number of lumbar punctures, method of approach and position of the spinal anesthesia, age, sex, surgical position, and the type of the surgery did not correlate with occurrence of acute back pain following spinal anesthesia.
a b s t r a c tIn this study, an effective cation exchanger was developed from the pine cone by citric acid modification and its hardness removal properties from the waters were investigated. For this purpose, ground pine cone samples were subjected to a citric acid modification following NaOH saponification. Both of the raw (RPC) and modified pine cone (MPC) samples were subjected to standardized hardness removal tests by shaking with hard waters. These tests showed that citric acid modification significantly increases the cation exchange capacity of the pine cone. Most suitable size fraction of pine cone was determined as -16 + 30 mesh (600 μm < x < 1200 μm). Also, citric acid modified product obtained from this fraction was used in a continuous system to remove hardness from water. The results of this study showed that the MPC can be used for hardness removal from waters as a cheap, durable and environment-friendly material. Finally, regeneration experiments showed that the MPC can be used for hardness removal from water repeatedly by a simple HCl regeneration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
