RESUMO

Introduction: In emergency surgeries, open abdomen or laparostomy, especially with perforated viscus, has been used primarily to prevent delayed ventral hernia, burst abdomen, and abdominal compartment syndrome. In the present study, the clinical and resuscitative factors that are linked with open abdomen morbidity are evaluated. Material and Methods: A retrospective analysis was done for all the subjects who were admitted at the tertiary care center between May 2020 and May 2022 for the open abdomen surgeries. These patients were examined to see whether they needed more postoperative care than usual, including the need for resuscitative treatments and other critical clinical indicators. Patients were evaluated if they had any complications. The data that were collected were analysed for any variance using analysis of variance considering P <.05 as significant. Results: A total of 100 subjects were analysed in this study. Forty nine patients had intra-abdominal sepsis of the 100 cases examined from historical case records and 1 had entero-cutaneous fistulas. These patients did not necessitate additional actions for intensive care unit care, resuscitation, an chest infection, extended hospital stay, or any disabilities compared to those who did not undergo laparotomy during the same period. In this group of patients with open abdomens, the immediate postoperative period was not linked to an increase in resuscitation efforts or a load on clinical staff. Once patients are stabilized, early definitive abdominal closure is advised to prevent problems associated to laparostomies. Conclusion: The quantity of initial fluid revival and the coagulation factors at the time of admission are not related to intra-abdominal sepsis and enteric fistula following laparostomy after significant abdominal injuries.

RESUMO

OBJECTIVES: The objectives of this study were to examine the role of reactive oxygen species and oxidative stress in peripheral neuropathy and behavioural pain responses in experimentally induced chronic constriction injury (CCI) of sciatic nerve of rat. Effect of N-acetyl-L-cysteine (NAC) administered intraperitoneally, was also investigated on CCI-induced neuropathic pain in rats. METHODS: Neuropathy was induced by CCI of the right sciatic nerve in ketamine anaesthetized rats. Effect of intraperitoneally administered NAC in rats was also investigated using nociceptive behavioural tests. Malondialdehyde, an index of oxidative stress and antioxidant enzymes was also estimated in ligated sciatic nerve. RESULTS: Behavioural tests, mechanical, thermal and cold stimuli confirmed the development of neuropathic pain after the CCI. The malondialdehyde levels of ligated sciatic nerves were significantly increased compared to non-ligated sciatic nerves (sham operated). The antioxidant enzyme reduced, glutathione was inhibited, while superoxide dismutase increased. However, catalase remained unaffected in the injured sciatic nerves. Intraperitoneal administration of NAC resulted in significant reduction of hyperalgesia in CCI-induced neuropathic rats. CONCLUSIONS: This study identifies antioxidants superoxide dismutase and reduced glutathione, and oxidative stress as important determinants of neuropathological and behavioural consequences of CCI-induced neuropathy, and NAC may be a potential candidate for alleviation of neuropathic pain.
