Pain is an everyday challenge during all surgeries and it is a chief postoperative complication, so pain management is a corner stone in anesthetic practice. Percutaneous nephrolithotomy PCNL surgeries are usually associated with acute postoperative pain. Ultrasound guided nerve block is considered a recent technique for pain management. it provides better visualization of the nerves and reduces the risk for complications e.g. unintended injury to adjacent structures. Erector spinae plane (ESP) block is a novel method of delivering postoperative analgesia after PCNL surgery, technique involves injecting local anaesthetic into the interfascial plane between the erector spinae muscle and the transverse processes.and is therefore devoid of major adverse effects like pneumothorax, spinal cord trauma, and hypotension that can occur with other types of blocks like thoracic paravertebral block (TPVB). The goal of this research was to determine the analgesic efficacy and safety of ultrasound-guided ESP. block done at T8 transverse process level in patients undergoing PCNL surgeries for intraoperative and postoperative analgesia.

This study aimed to evaluate the proportion of contraception users among Lebanese youth, and the extent of knowledge and perception on birth control; and to raise awareness and sensitise young adults to sexual health, which remains taboo in Lebanon. The 30-item questionnaire was broadcasted to students in private and public universities in Lebanon, through social media and it collected information on contraception use and student knowledge. Over 30% of responders were medical students, and 41% have ever used contraceptives (mostly women); among which, 52.1% for contraception versus 47.9% for medical reasons. According to responders, the pill ranked high in terms of effectiveness (72.4% of responders perceive the pill as effective), followed by the male condom (69.1%) and the hormonal intrauterine device (29.6%). Some would not use contraception in the future, for religious reasons (30.8%) or for fear of complications (46.2%); indeed, around a third of contraceptive users (all female) have experienced adverse effects. Finally, students expressed concern about long-term complications of contraceptive use (pulmonary embolism/phlebitis, breast/endometrial/ovarian cancer, stroke, depression and myocardial infarction). Though less frequent than in the Western world, contraception use in Lebanon is non-negligible and gaps in university students’ knowledge on contraception were identified; which should prompt sexual education and family planning initiatives in Lebanon.
