The role of the lived body during the integration of the traumatic experience of the sternotomy scar: A case study.
Open heart surgery is a potentially traumatic experience for patients, thus posing a real risk to both the patient's physical and mental health as well as bodily integrity. All of these can greatly affect the emotional relationship to the sternotomy scar, the physical aspect of self-representation. Sternotomy scars mark patients for life, yet our knowledge of patients' subjective experiences is unknown. ⋯ Based on our study, it seems that the corporeal dimension of posttraumatic growth may develop after the traumatic experience of heart surgery, in which bodily intimacy with oneself and Significant Others plays a major role. In this case study, the objective reality of the heart as "sick" flesh and the "broken, pierced" bone (Körper), as well as the dissociation-and then its integration-of the lived, living body experience (Leib) are outlined. Our case study was analysed in the theoretical framework of phenomenology and psychoanalysis.

Impaired glymphatic clearance of cerebral metabolic products and fluids contribute to traumatic and ischemic brain edema and neurodegeneration in preclinical models. Glymphatic perivascular cerebrospinal fluid flow varies between anesthetics possibly due to changes in vasomotor tone and thereby in the dynamics of the periarterial cerebrospinal fluid (CSF)-containing space. To better understand the influence of anesthetics and carbon dioxide levels on CSF dynamics, this study examined the effect of periarterial size modulation on CSF distribution by changing blood carbon dioxide levels and anesthetic regimens with opposing vasomotor influences: vasoconstrictive ketamine-dexmedetomidine (K/DEX) and vasodilatory isoflurane. ⋯ K/DEX and isoflurane overrode carbon dioxide as a regulator of CSF flow. K/DEX could be used to preserve CSF space and dynamics in hypercapnia, whereas hyperventilation was insufficient to increase cerebral CSF perfusion under isoflurane.

The anesthesiologist's guide to swine trauma physiology research: a report of two decades of experience from the experimental traumatology laboratory.
Swine are one of the major animal species used in translational research, with unique advantages given the similar anatomic and physiologic characteristics as man, but the investigator needs to be familiar with important differences. This article targets clinical anesthesiologists who are proficient in human monitoring. We summarize our experience during the last two decades, with the aim to facilitate for clinical and non-clinical researchers to improve in porcine research. ⋯ Swine share anatomical and physiological features with man, which allows for seamless utilization of clinical monitoring equipment, medication, and physiological considerations.
