Ischemia and reperfusion injury due to tourniquet application during arthroscopy is a well known problem. This study aimed to compare the effects of dexmedetomidine and ketamine on hemodynamic and respiratory variables and on total anti-oxidant status (TAS), total oxidant status (TOS) and malondialdehyde (MDA) as markers of ischemia-reperfusion injury. ⋯ In patients undergoing arthroscopy under spinal anesthesia, dexmedetomidine had effects similar to ketamine, led to insignificant alterations in hemodynamic and respiratory variables during surgery and had comparable effects on ischemia-reperfusion injury. Thus, we think that dexmedetomidine can be a safe alternative to ketamine as an intraoperative sedative.

In this double-blind prospective clinical study, we investigated the effects of fentanyl and dexmedetomidine as adjuvant agents in supratentorial craniotomies on the following: hemodynamic changes during perioperative and recovery periods, brain edema perioperatively, recovery times and side effects, such as hypertension, shivering, nausea and vomiting. ⋯ In our study, we found that dexmedetomidine controlled the hemodynamic changes better than fentanyl perioperatively, after extubation and during the early postoperative period. Our results suggest that that dexmedetomidine is safer and more effective in controlling hemodynamic changes during surgical stimulation than the standard agents used in neuroanesthesia.

Spontaneous pneumothorax is a disease that may cause serious respiratory distress and can be a life-threatening condition. A total of 1.3% of all spontaneous pneumothorax cases are simultaneous bilateral spontaneous pneumothorax (SBSP). In this study, because of its rarity, we discuss SBSP cases in light of previously reported cases. ⋯ SBSP could be a life-threatening condition; therefore, urgent diagnosis and appropriate treatment of this condition can save patients' lives.

In this study, we compared the clinical effects of combined doses of ropivacaine and clonidine. ⋯ In summary, our study revealed that clonidine can be added to ropivacaine for spinal anesthesia in surgical interventions to obtain deeper and longer sensory and motor block. However, hypotension, bradycardia and sedation should be monitored closely.

In this study, we investigated the safety and effectiveness of epidural saline injection to prevent post-dural puncture headache (PDPH) in patients with acute lymphoblastic leukemia (ALL). ⋯ Our study shows that isotonic saline injection into the epidural space after LP is a safe and effective approach to prevent PDPH and related complications.
